I am an ECET major, and this video series is the best one I have found for these topics. It makes them very simple and easy to understand. Now I can easily teach these concepts to others and even refresh my own respect for them easily. Thanks.
i love this demonstration! thanks for opening up the capacitor....always helps to know what these things are made of. that demo of a crude capacitor (plastic bottle and aluminum foil) is an excellent way to demonstrate the capacitor's properties.
Thanks. I have been doing some electronics stuff as a hobby but I have been confused. After watching a bunch if these videos I am back on track with no more troubles.
thanks I am from India and have been looking for the functionality of various electronic components and in India we have bee taught in a fashion where there is literally no scope of learning although we have been thought conceptually about various things but no illustration , keep up the good work
I just made one at my EMS station, we we're bored, and as everyone else was sittin around thinkin of something to do, and i got some alum. foil, a plastic Folgers can (always around lmao), some spare wire from the light bar switch we just did on our fly car, PVC pipe, and a polyester windbreaker, and it worked! Everyone here was gettin pretty good kicks out of it, even though it didn't work that well, i kinda made it in a hurry, we'll see if we can make it better, thanks for killing boredom! XD
@Ne555N You use the negative lead of the capacitor as the ground. You don't need to ground back to a battery since the capacitor is used a temporary storage for the current.
A Leyden jar is a capacitor. All a capacitor is, is two plates of something conductive connected to electrical terminals of different voltages, that are close, but not in contact with each other. A charge is built up between the plates. The way the common electrolytic capacitor differs from a plate capacitor is basically just that the plates are rolled up instead of flat, facing each other. Making one is, thus, really simple. Read the Wikipedia page on the electrolytic capacitor for more info.
A Capacitor is basically two plates standing side-by-side each other. If you apply a voltage threw the capacitor, it will generate an electric field that will add electrons to one plate and remove electrons from another. Capacitors have capacitance which is measured in farads, or the magnitude of charge (in coulombs) on one plate when you apply a voltage threw the capacitor. Now, to calculate capacitance, learn Gauss' laws.
The use of the resistor is to reduce/restrict the full high voltage from the capacitor. LEDs actually are only able to handle 1-4 volts depending on the specs and overpowering them will burn them out. :)
Gives a basic idea at the end with the LED. The strips of metal have a stored potential difference. When you apply a load or short them out, the electrons flow and neutralize the potential differences.
You see the strip at 1:58? It stores eletric conduction on thoes strips, they are charged, and because they have large areas, and they are usually filld whit some electrolit they can store eletricity by a high resistance to esceping electrons.
@Oshiba88 The voltage is the maximum the capacitor can handle without damage. As such, you could use a 2.2uF cap rated for 16V, 25V, 35V or even higher, provided it will physically fit.
@ryangolf1212 so you have a place for the electrons to go a capacitor consists of two oppositely charged plates. To get there from neutral foil you need to connect to ground on one side
The battery generates a voltage from a chemical reaction, a capacitor first needs to charge up and then delivers the charge, but it does not generate a voltage by itself. When you charge a battery, you are reversing a chemical reaction that afterwards is going to give you power, but a capacitor keeps the charge without a chemical reaction involved, it just keeps it as an electric field that stores energy.
good informative video. But I still have a question. When you make the laden (sp) jar, where is the actual storing of voltage energy, cause it seems from what you showed is that you created static electricity and let it flow into the center conductor, then you touched the center conductor to the outside conductor (after stopping the supply of electrical energy to the inner conductor), and there was a discharge as shown by the spark. So, if this showed that the inner metal wrapper held a charge for a while, then does that mean that even a wire should be itself hold a charge for a while, for example, if I connect one end of a wire to a battery and then take the battery away, will the wire hold a charge for a split second? If so, then is it the cylindrical design of the laden jar that causes the charge to be sustained for a longer time?
Batteries store energy as chemical potential, then convert it to electrical energy when a load is put across it and some batteries can do this very quickly (lead acid car battery for example) capacitors however store energy as a potential difference of voltage across the plates, one plate actually has more electrons than the other, when Colin said the capacitor equalizes its charge, the excess electrons are just moving back to the other plate. Basically the difference is how the energy is stored
@TheRadioControlKid capacitors tend to release all their charge almost instantly. capacitors also tend to hold high voltages although not all of them do. however, supercapacitors can store almost as much energy as a small battery experiment: go to radioshack and go to the back where all the component parts are find the biggest cap they sell (with the highest uF) and buy it, and charge it to 3 volts with two batterys, and see how long it willpower an led. not too long...
So capacitors discharge when they are "full" or when they have enough energy? Or do they discharge when they get some kind of pulse from the outside? Because on PCB's the caps are always connected to the circuit, not like in the video where he connected them once the cap was full.
CookieCraftMedia They discharge because the electrons have a suitable path to travel. Normally, air is not a conductor but it will behave as one if there is enough voltage between the two conductors. If you bring the two conductors closer, the discharge will have a faster rythm or tempo.
CookieCraftMedia this is a good question tht still has not been answered because is not like the cap acts as a npn transistor or a pnp for this matter so how does this cap actually come into play? in a arduino uno you will notice those 2 big cap by the power jack and they are connected obvsly but when do they work ? if i power the uno with 5v(usb), 9v(jack) or 12v (VIN) what are this caps doing in place? when a transistor or voltage divider can and will do the same job?! and if im not mistaking there is a voltage divider in place for 3.3v (PWR Pin) and a resistor in place for regulating energy down to 5v (PWR Pin) so again why the CAP? and two at that if i was able to connect a motor directly to its GPP and work just fine then i wud have made a guess and said that those CAP are there to act as a reservoir of energy to contain the power needed to energize its motors like Servo Stepper or DC motors but i know that Arduino aren't good at powering motors directly after its a Micro controller not a Driver Controller right and on those you do see this big Caps you notice in the Arduino uno so can someone share some knowledge and shine light on this topic? thanks in advance
so is thee a component that can be change in the mcu to let it have more mA so that it can actually drive a motor it self what type of upgrade can be done ?
CookieCraftMedia Whenever there is a charge on a capacitor, it will try to discharge itself. You can discharge it by shorting the leads with a piece of wire (not recommended for higher capacity caps charged to a few volts though) or a resistor, but since nothing is a perfect isolator (even air is not), the cap will discharge slowly over time. It will take more/less time depending on the resistance, capacity and initial charge. So to answer your initial question, capacitors discharge whenever there is energy stored and it has a path to discharge.
B10S But when the capacitor is on a solid chip, there is no "Hand" which can short the leads out. So how is the charging and discharging controlled, when it is mounted fixed?
As of now, Capacitors work better to store electricity and discharge it quickly, Batteries discharge slowly. Capacitors also "Leak" at a much higher rate than batteries.
The resistor is used reduce the current passing through the LED and prevent the LED from burning out. Without the resistor, the capacitor would discharge almost instantaneously assuming the LED and wires have near zero resistance. That is not ignorance. That is curiosity which is a good thing.
Capacitors can store potential (voltage) for a short amount of time, usually a few seconds for small capacitors. A battery on the other hand, will store potential for a long time until it gets discharge. They are very different!
Batteries involve a chemical reaction in the presence of two dis-similar conductors involving an electrolyte of some kind (a manganese dioxide coated carbon cathode and zinc anode with a zinc chloride and ammonium chloride as an electrolyte for example, there's tons of different kinds of batteries.) A capacitor is just a gap between conductors made of some dielectric, they're better at storing high voltages in small quantities and discharging/charging very quickly.
I'm pretty sure what happens is that the charge builds up on one of the metal sheets, creating a charge density. When the sheet is connected to the rest of a circuit, the charges jump, creating flux on the other sheet, and the other side of the circuit
LED's have a maximum current(A) they can withstand before burning out. It is usually around 20 mA or so. 9V batteries have something around 300mA of current. 300 is obviously a lot higher than 20 so you need a resistor to drop the current down to something that won't make the LED burn out.
@TheRadioControlKid the power is stored inside the chemicals in the battery, that's where the power comes from, capacitors only hold a minuscule about of charge, in other words if you were to power somthing, it would only last a a mircrosecond with the small caps, and you might get (at the most) a few seconds with a much MUCH large capacitor. a
Collin's Since you introduce Michael Farad and Capacitance; try giving a demonstration of Faraday's first electric circular motion. His experiment is considered the first motor. It is not difficult to create. I think it would freak out most of your audience. After they see how it is done; most will try to build one. All you need is salt water (he used mercury), battery, permanent magnet, some solid copper wire and a simple support. The whole experiment is profound but simple.
Well, if you want something for a really long time, you can look into SuperCapacitors, these run in the Farad range. Make sure you get one without super low ESR!
A capacitor is most commonly used to avoid damage to other component in case of open circuit...for example if the electricity cuts off while you are using your desktop computer (assuming it has no other external battery supply) it avoids damages to important chips by gradually releasing it's energy stored, and not letting the current to suddently drop to 0.
your basically separating a negative charge from a positive charge to make potential energy and than releasing that potential energy whenever you feel like it, this process is MUCH quicker than a battery that stores a chemical charge. cap.s are now being researched to make ultracapacitors that can store the same amount of energy as a battery, but they would be able to release that energy in seconds which would be awesome for soo many things, we wouldn't even need battery's anymore.
I would have to agree! Very cool, I knew how they worked before this, but still a good piece of work! I could watch this stuff on TV all day. Problem is...TV programming is for simpletons!
im not a physics expert, but I believe it works by holding the charge of electricity. Potential energy is built up by the PVC pipe and is stored between the foil. the outer and inner foil keep the potential energy until there is a ground for them to dump out of.
I found out that if you make a series circuit with a speaker and a motor, you can hear the motor through the speaker using electrical noise. But if you connect a capacitor in series on its own and the out the motor in paralel, you won't here any noise because the capacitor is basically a filter
its a high voltage pulse capacitor its about the size of a led acid battery for a car. took it apart and its only a bunch of ceramic plates with silver foil in between
So a resistor is like a regulator than? It won't allow all of the charge to go at once or over a certain level or voltage? Could a capacitor hold a charge for like a few days or longer? Sorry for all the questions haha. I'm just pretty curious. I thinking about going into electrical engineering next semester.
A regular battery releases energy as time passes. Almost like a light that's been left on. Capacitors collect and stow away energy, therefore it does not escape unless a current is being passed.
all by itself? a 555 timer circuit would charge and release a capacitor, but thats the timing feature do you want to collect the electricity that is released?
NO, a battery is a cell with an integrated chemical oxidation-reduction reaction, in which the electrons flow from a substance (commonly a metal like zinc or lithium) to another (like manganese dioxide), and they do it through the circuit of the device you use the batteries in.
Do a search for the "Baghdad Battery" or "Egyptian Battery" date to be from the 3rd cetury B.C. , yes Pieter van Musschenbroek's capacitor is a very close copy.
When and how we want to determine the size and type of capacitors to be installed in the circuit,what is the characteristics and how do I calculate the required capacitor in the circuit?
The video is very enjoyable and easy to follow, great video. But the music is unpleasant when you are talking. If you have to use the music please adjust the volume just right so that it stays as background music. And again GREAT Video and demonstration.
Yes, but I didn't say a dielectric causes an electric field, I said it allows an electric field to be established. Indeed air can also be a dielectric, but the point I made was your exclusion of it while explaining it to Tom. Correct, that was my typo, I meant to write 'protons' which would indeed equal the net 0 charge, however, in establishing an electric field with a *battery* (polarized, unless it is an AC power source) adding electrons to the receiving plate will create an efield
It's a pity we don't see so much of Collin Cunnigham on TH-cam any more. He's a great video presenter... one of the best.
For a video uploaded in 2009 this is before its time quality wise.
its a timeless video
nice friendly inventors atmosphere. where we can just dream together uninhibitted.
I am an ECET major, and this video series is the best one I have found for these topics. It makes them very simple and easy to understand. Now I can easily teach these concepts to others and even refresh my own respect for them easily.

great teacher. I don't know how he is so humble.
I have read and seen many video and they weren't able to translate or explain, things like you do; please don't stop making videos.
Thanks. I have been doing some electronics stuff as a hobby but I have been confused. After watching a bunch if these videos I am back on track with no more troubles.
You are the one of the best practical teacher...
Very nice group of videos. I've learnt a few things this evening. I liked the bit of history thrown in to show the roots of progress. Thanks
I love this guy, he explain very well and even beginners shall easily understand the explanation. Nice One Again!
this guy is the best one to teach electronics his funny way of teaching makes people understand
the intro had me laughing 😂. amazing video yet again from collin and the make crew
thanks I am from India and have been looking for the functionality of various electronic components and in India we have bee taught in a fashion where there is literally no scope of learning although we have been thought conceptually about various things but no illustration , keep up the good work
I must admit .. you are the best ,, you explain things the way it should .. thanks for taking your time to do it keep doing it .. God Bless
youre the best teacher ever. i wish u could have been my high school teacher
I just made one at my EMS station, we we're bored, and as everyone else was sittin around thinkin of something to do, and i got some alum. foil, a plastic Folgers can (always around lmao), some spare wire from the light bar switch we just did on our fly car, PVC pipe, and a polyester windbreaker, and it worked!

good video. Thanks for putting it in HD to, it looks so much better.
0:19 *notices It's copyrighted music*
lol
Well, calling it “music” is a stretch...
Collin is something precious and we must protect him. ;)
@Ne555N You use the negative lead of the capacitor as the ground. You don't need to ground back to a battery since the capacitor is used a temporary storage for the current.
I am with every body saying make more videos like this. That was very informative.
Great Work, please keep doing it. You instruct millions with your know-aged! Thanks and best regards

This video is pretty cool.
Five stars all the way.
@dime363 the rechargeable batteries act almost the same as the capacitor but the purpose of a capacitor is mainly for filtering and batteries don't

Such a great video to show basic concepts of a capacitor! I'm gonna show it in my lab
is it just me or the audio is a bit badly mixed ? the music is sometimes too loud . my 2 cents ;) very very good video nonetheless
Yes, his lower notes are a bit loud and they interfere with his voice.
I love that type of videos: simple, fun and instructive

In Dutch this device is called a "Leidse fles", which "Leidse" is derived from a city and "fles" means bottle, or jar.
Batteries involve a chemical reaction in the presence of two dis-similar conductors involving an electrolyte of some kind (a manganese dioxide coated carbon cathode and zinc anode with a zinc chloride and ammonium chloride as an electrolyte for example, there's tons of different kinds of batteries.)

Great video! Can you explain and dissect a Super-capacitor/ultra-capacitor.
If Capacitors are meant to hold a charge... why do we have batteries?
A very interesting and informative video - got to watch all the others now! Thanks for posting.

@TenFoldDamage - Well, i'm glad that I read your post, because if I'd seen "mF" I would certainly have thought that it meant milli-Farad.

I would have to agree! Very cool, I knew how they worked before this, but still a good piece of work!
I could watch this stuff on TV all day.

a great demonstration of intelligence, thanks man
im not a physics expert, but I believe it works by holding the charge of electricity. Potential energy is built up by the PVC pipe and is stored between the foil. the outer and inner foil keep the potential energy until there is a ground for them to dump out of.

@lwanatt I think when one side gains electrons, they are naturally going to repel electrons from the other side.
I so much like these series, even though I'm perfectly aware of the components discuissed ^^
Excellent video and explanation
its a high voltage pulse capacitor its about the size of a led acid battery for a car. took it apart and its only a bunch of ceramic plates with silver foil in between
i cant help stairing at his head for all his videos
School's don't teach like this!! :/
So a resistor is like a regulator than? It won't allow all of the charge to go at once or over a certain level or voltage? Could a capacitor hold a charge for like a few days or longer? Sorry for all the questions haha. I'm just pretty curious. I thinking about going into electrical engineering next semester.
Great video. Thank you for posting this video up.
Thank you for these videos. Learning so much!
It would be cool to see inside those other capacitors.
A regular battery releases energy as time passes. Almost like a light that's been left on. Capacitors collect and stow away energy, therefore it does not escape unless a current is being passed.
thanks for all the lessons here! really helpfull!!
Based on these informations i will be able to build my own capcitors.
Thank you!
Thank you very much man, you are one of the best teachers i will have. :)
Thanks! It all makes total sense now!
When ground is applied, was it connect to a small DC battery or to what was it connected?
all by itself?
a 555 timer circuit would charge and release a capacitor, but thats the timing feature
do you want to collect the electricity that is released?
Why is the PVC pipe attached to ground? Wouldn't the built up charge favor ground more than the capacitor? Thanks
Looking forward to studying this next year!
NO, a battery is a cell with an integrated chemical oxidation-reduction reaction, in which the electrons flow from a substance (commonly a metal like zinc or lithium) to another (like manganese dioxide), and they do it through the circuit of the device you use the batteries in.
Do a search for the "Baghdad Battery" or "Egyptian Battery" date to be from the 3rd cetury B.C. , yes Pieter van Musschenbroek's capacitor is a very close copy.
When and how we want to determine the size and type of capacitors to be installed in the circuit,what is the characteristics and how do I calculate the required capacitor in the circuit?
the music is awesome in this!
This is an awesome video and your presentation was totally clear and understandable. Thanks for posting it. Cheers.
The video is very enjoyable and easy to follow, great video. But the music is unpleasant when you are talking. If you have to use the music please adjust the volume just right so that it stays as background music. And again GREAT Video and demonstration.
Yes, but I didn't say a dielectric causes an electric field, I said it allows an electric field to be established. Indeed air can also be a dielectric, but the point I made was your exclusion of it while explaining it to Tom.
Correct, that was my typo, I meant to write 'protons' which would indeed equal the net 0 charge, however, in establishing an electric field with a *battery* (polarized, unless it is an AC power source) adding electrons to the receiving plate will create an efield
I really enjoy your work. Thank you.
Ever played with the capacitor inside a flash camera? Those things are wicked...
