I was modifying one of my guitar pedals while watching this and it was very helpful to make me remember and relearn all that stuff I learned about 15 years ago and all forgot since lol Nice and clear explanations! 👌🤘❤️
So you would use a capacitor if you expect a sudden voltage drop from another component in the same loop drawing power and you want to maintain a constant available flow of current. You would never learn that if you watched this video.
Ravi Krishnan I was thinking the same thing hahaha. I know a capacitor holds a charge, but why is that needed in a circuit when you will get a charge regardless with a power source?
I was hoping for a little bit more of an in-depth view of what a capacitors job is or what kind of task you can do with it. Having a led "dim out" doesn't seem very useful. Is there anything more to it? If not, it seems like a rather useless component
I believe the capacitor can be viewed at as some kind of a turbo. It stores a small amount of current that is instantly given out. This would be useful for things such as motors that use PMW that quickly turn on and off
Hi thanks for the question and sorry for getting back so late, Yes I can go a bit more in depth. Capacitors will charge after a certain time. Googling a the math behind it will yield some basic algebra. There are circuits called RC Circuits. Guess what RC stands for! R for Resistor and C for capacitor! By changing the values of R and C in the circuit you can change the discharge time! This constant is called "Tau", Tau can be calculated by doing R*C. RC circuits can be combined with other components to create oscillators so they are pretty cool! Another thing is that in a DC circuit a capacitor will charge and then will stop current flowing to it because it does not need any more charge. Yes Half-Blood Prince is sort of right. Capacitors have an extremely low resistance so when you have a large capacitor with a lot of charge and need to discharge it there will be a massive voltage spike! If you discharge it using a metal rod. The metal rod has a very low resistance!
I wish you would have explained it with some drawings. Not necessarily using oscilloscope. Hand drawing will suffice. It's difficult to see how fast the capacitor is charging or discharging
Hello. Can I know i make some ac to dc rectifying unit for my motorcycle with a 25v capacitor for power on 12v 40w led fog light. But its ok when at the rpm supply but at the idle its flickering. Can i stop that using 4700uf or using larger capacitor ?
I have a basic question about installing capacitors. I'm putting LED lights on a snowblower after finding some instructional videos on TH-cam. My power supply is the engine's stator that produces AC so I'm wiring a bridge rectifier and two capacitors into the circuit to create smooth DC power to the LEDs. My circuit is: AC wire from the stator through a fuse to the AC post of the rectifier. The rectifier's other AC post is grounded to the frame. The rectifier's DC negative goes to the black wire of the LEDs and the rectifier's DC positive goes to the red wire of the LEDs (through a switch). The instructions about installing capacitors say: "Using two 2200mfd 50v capacitors may be needed to clean up voltage ripple that comes off of the DC output on your bridge rectifier. Some LED lights are sensitive to this ripple and may fail prematurely. Simple adding these capacitors in parallel on the DC output side of the bridge rectifier is a good precaution. Wire in the Capacitor(s) between the LED light(s) and the bridge rectifier. So the postive and negative of the bridge rectifier will go to the positive and negative of the capacitor. Then the positive and negative of the capacitor then get wired to the LED(s) positive and negative." I'm not sure if I'm interpreting the instructions correctly. The original poster has not responded to my request for clarification and seems to be gone from TH-cam. I subscribed to your channel when I found your video on "How to Use a Capacitor." Here's my question: Where should the capacitors go and how should they be wired to perform their function? In other words, if one goes on each line, does it go For the first capacitor: 1) DC negative to 2) first capacitor negative side then 3) out the positive side of that capacitor to 4) black wire of the LEDs? (or should it go to the red wire of the LEDs?) and For the second capacitor: 1) DC positive to 2) second capacitor positive side then 3) out the negative side of that capacitor to 4) red wire of the LEDs? (or should it go to the black wire of the LEDs?) I would really appreciate any help you can provide.
As you've figured out by now, I know very little about capacitors. Also, I don't know the symbols to use when drawing a schematic or how to post a photo here in the comments section. To try to get info to you so you can help me, I uploaded a video of the pencil drawing I made of my wiring project. Please don't laugh at it because even I admit it looks like something drawn by a grade schooler! Anyway if you look under my channel, you will find a video called "I need capacitor advice." Please watch it and let me know if you can help me. Thanks!
great informative video thanx!. Can u use it on 220V AC circuit as well? I'm trying to find a solution where a magnetic solenoid valve after power off still open for 15-20 sec? Is there a way to do that?
It can store only DC, there are DC solenoid valves but it is job for profesional. You can also use power inverter+some supercapacitor to have AC for some extra time after power loss.
can the resistor be used on either the positve or negative side of the circuit? I am an amatuer in this, still trying to learn the basics, in your breadboard i think your resistor is on the negative side while in your drawn circuit it was on the positive side. or did i get all this wrong? resistors are not polarity sensitive, and i think LEDs too. but it doesn't matter which side you put a resistor right?
Yes, you can place the resistor on either side of the LED as it will still prevent too much current from flowing through and causing the LED to burn itself out.
One question sir... is the series resistor really needed after the capacitor? what if iLL not add a resistor and go straight to the load.. lets say the load is an LED.. will the Led still light up without problem?
i have electrolytic capacitors mounted on electronic devices from 1990, how long can these devices remain unused and without the electrolytic capacitors failing due to disuse?
hello, i am new to this , hope you can answer my question and its not too long winded for you to reply :), . You used a plug in device for the current, if it was a battery say a 5 volt battery (if there is actually one) the 'ground' would be to the anode or '-' of the battery and were you have the 5 volts in your drawing that cable would run to the positive terminal of the battery? thanks in advance
Raghuveer Shetti. hi remember that caps in series do not add like resistors but they add inversely. They will all have the same charge on them. By using a voltage divider eq you can find the drop across each cap. when connecting polarized caps in series remember to connect plus to minus and so on. Also voltage is also dependent on the charge of the caps, Q measured in coulombs.
ps i guess its use in this instance is just to give a nice slow down of the light. pss have you got the math calculations for this simple circuit ? it would help my understanding more ?
Rebaona Mosiane if the capacitor is not in the shape of a can similar to the black one I use in the video then it's a code to a correspondencing value of .22uF so it's about 3x the capacitance of the one in the video. What's the application for it if you don't mind me asking?
Hey its because capacitors can dump a lot of current very fast given a low resistance across it's terminal. Capacitors have a much smaller internal resistance than that of a battery. Capacitors can also store a lot of energy so when it gets discharged watch out! If you have ever shorted the ends of a capacitor you'll sometimes see a very large spark, this is because of the current moving very fast through that short wanting to neutralize the charge on the plates. So if you need a large amount of energy in a short amount of time, a capacitor is the way to go, not a battery. That's what can supply so much current to create that massive magnetic field created by the coils. The magnetic field is then used to propel an object very fast!!!
@@MostElectronics Can I use a PWM signal to control a capacitor? I want to have the capacitor discharge at a certain time, so would I be able to vary it's frequency?
Anyone no why disk capacitors use different number for the same value,like a .01 mfd cap electrolytic,disk cap will say 103 ,instead of .01 mfd both our the same mfd,s and same voltage ,but the 103 = .01 mfd is the,only one.I no ,what if the disk says 104 I don't no what are the Mrs number is does anyone.no how to convert disk numbers into electrolytic Mrs numders.
But if you can run the circuit without a capacitor the light still works fine with the resistor. So what was the purpose of the capacitor in this circuit ?
Loooooool , for the fact that if accidentally you have a black out to your ellectricity cicuit than the capacitor will help the light to stay open for some seconds . hahahaha

You could have used 2000uF for showing the fade clearly
One the cap charges the current stops flowing? I just thought it continually blowed though to the led
what was the purpose of hooking up the capacitor to ground? I can't understand what ground is used for
To provide a complete circuit when we charge the capacitor.
can it be used in a circuit for de-acceleration? like so X slowly slows down? x as in like an rc boat or car.
If it had a high farad yes
