I had a mentor that said the ability of a teacher is not judged by what they know, but how much of what they know they can teach and how effectively they can teach it.
Jesus, I wish I had this kind of explanation on my university, After lots of struggling understanding this I finally understand it very well. Thank you very much!
Nice :) You´re in the University and they cannot really explain to you what a series circuit it´s like? _That´s hard!! Man, when you´ll get to the point of Kirchoff´s Laws and some other physics material, you will find out that series circuits are easy... or at least easier.. I wish you very good luck :)
Absolutely love these videos! The metaphors used make it so simple to understand, really helping me understand the stuff my teachers just aren't explaining simply! Thanks so much!
I started watching your Basics series and, as someone whom is nowhere a genius when it comes to electricity, this made questions I've had for decades seem so common sense. Thanks for explaining things in laymen's terms!
*summary:* - if you have n resistors in a series, the total resistance in the circuit is the sum of them - current is the same throughout the circuit (think as good as weakest link) - if you have n voltage sources in a series, the total voltage across the circuit is the sum of them - voltage will vary throughout the circuit (it depends on your two points of reference) - resistors take some of the energy of electrons passing through them and convert them into heat
Thank you! Having online classes are already difficult given the less amount of time our professors have to spend during synchronous classes. I can submit my paper for our laboratory experiment with confidence despite just having been given the task alone without discussing anything about the topic.
This is the best!! I used today at work when I had to convert 2V signal to 4 mA signal because the sensor was taking mA and our controller was able to send only 2-10VDC signal and I wasn’t sure how to connect the resistor. Then I watched the video at work, understood everything and everything worked after I placed the 500 Ohms resistor in series. Thank you very much!
Currently in Army BET lab, and this stuff went over my head today. Probably would have helped if it wasn't a class done completely by computer with minimal instructor guidance, but that's a complaint for the AAR. Thank you so much for making these videos- I might actually graduate this course.

This is a great series of videos. Easily followed. Pretty thorough. But, wow! Are they ever repetitive. I guess you wanted every video to stand on its own but I sure would prefer to have a series of trimmed videos.
Let me tell you that i enjoyed your explanation and graphics. Well Done !:) Resume: _Series circuits add up to their values and the current is always the same_Unless the measurement is between two load/resistor terminals. In that case, what is being measured is the load/resistor and not the serial circuit_
I’m on Christmas break for college and I’m here watching videos to have knowledge for next semester. I can’t believe I’m saying this but I am a nerd 😂.
Thanks Paul, I have a question, if we apply the same concept about more resistance gives less current, into a circuit in a house. Why when we have a lot of items working in the same time (resistor is high), the current in the circuit gets overloaded and the circuit breaker trips. Shouldnt the current passing that circuit be less due to the high resistance? Which means CB should not trip. Hope my question make sense 😅
@@EngineeringMindset hloo sir, if in house there is a parallel connecting,then voltage same for all but current split as more as aploncse are connect. So this mean that appliances work on low current or we can say current not influence as much as voltage.plz and. Me
Man, I love your explanations. Please give us more. I am now making my own playlists from your videos and really absorb everything. I even got a notebook and take notes. Is Paypal the only way to buy you a beer ? (I just hate paypal) . Cheers . Keep up the wonderful work.
Where were these videos when I was in highschool smh I would've loved science classes so much more. I love science and learning but holy cow was my education pisspoor. Thank you for the content!!
Hi, love the video! Have a question though. At the 2:30min mark you show two examples - the left one is 9V battery, 400 Ohm resistor, LED and measured 18.7mA, the right one - 9V battery, 900 Ohm resistor, LED and measured 7.9mA. If there were no LEDs the measurements would have been - left 9/400=22.5mA, right 9/900=10mA. I have done some research and found that for those measurements to be true the left LED should be a yellow LED with a voltage rating of 1.8V doing best performance at 22mA - 1.8V/0.022A=81 Ohm, therefore 9V/(400+81)=18.7mA and the right one should be something like a white LED rated at 3.2V, going at 13-14mA, so 3.2V/0.0135A=237 Ohm, therefore 9V/(900+237)=7.9mA. Is my logic correct, because those measurements battled me hard??
It's not a given that it's a 9 volt that's just a basic shape to use for the model. Your supposed to find the voltage in that scenario by converting the miliamps to amps, 18.7 x 1000 and then x 400 ohms gives you a 7.48 volt battery
great video ! Does it mean if We used conventional flow from positive to negative, the resistant will be on the positive branch ? I am confused with the diagram drawings
He explains thing very well. I thought that video was going to explain DC Series Circuits but the entire thing was about resistors. Useful but not what the title claimed.
Hi ;) I understand what you are saying, but i think the best way for you to understand how a series circuits works it´s just thinking about this: In a series circuit the current that flows it´s always the same.... The only thing that can happen is that there are voltage drops. And that is why if you measure between those resistances, there will always be voltage drops. ..But the electric current is always the same... And remember this: In circuits of this type, what is in series will add up the values. ..As is the case with resistances ...I think very briefly, this is a series circuit ..
Great videos! It would be nice if you could so nicely explain a) transistors, and b) rectifiers also while youre in a go, which are hardest for me to learn via youtube :P Thx!
How´s that? Do the same way he did ! The cable must be isolated... Then, before you connect everything to the battery, first connect the resistor with the cable. Ok, now, you can connect the cable points to the battery!! When you´ll be ready to measure, grab you Multimeter put it in the right measure position,=Voltage,Current or resistence=, and put the Multimeter terminals on each side of the resistor. And this is how you will have a read ! PS: In that especific case, you can measure the voltage but also the current. So, you apply a known formula__Ohm´s LAw_ The voltage you already know= 9Volts. Now you want to know the Current_! SO, OHm´s Law:: Voltage= Restitance * Current__!!!!! To know now the current::: ::::::: Current = Voltage / Resitance::::: So, Volts= 9 volts / Resistance=10 ohm = TOTAL= 0.9 Amper (current). Sorry for all this, but i felt that you might need it ;)
Sorry if this is a confusing or dumb. When he talks about watts in the end of the video, is he talking about it being the power consumption of the all the resistors? Or if he were to put a light bulb on to the circuit, That the bulb would be powered with how ever many watts with a 9V battery at the end of the of the circuit.
In the circuit with an led and resistors you calculate the current as if the resistors were connected to 9v directly. Shouldn't it be 6v because the led is dissipating 3v?
Yes, but that would make the video too complicated, especially since LED voltages vary quite alot depending on type. Ignoring the LED voltage in this case also is an error on the "safe" side, because in reality the LED will get less current than calculated.
@The Engineering Mindset I have a question. If at 8:09 the Voltage drop accross the resistor is 9 Volts, then doesn't that mean that the circuit has lost all of it's potential difference and then there is no longer any current running through the wire after the resistor because there is no longer a difference in voltage? Thank you for your consideration of my question, I am really stumped and have throughly enjoyed your videos enough to want to endorse you. That's how much I appreciate you
Because if the supply voltage is 9 volts, then if the voltage drops by 9 volts, then shouldn't there be net 0 volts left after the resistor? Thank you so much for the help.
After the resistor, the voltage is 0v, because we can only measure the difference in voltage across two points. So if we measure with reference to ground which is 0V and the other probe is also connected to ground then there is no difference so we would read 0V. Maybe if you had a very very precise multimeter you could read like 0.001V or something because the wire will have some resistance, unless you measure at exactly the same point. The voltage difference is still across the load (resistor) so current will still flow, the electrons must flow back to complete the circuit and keep the chemical reaction of the battery going.
So it doesn't matter where within the circuit that the resistors are placed? I've seen diagrams that show a simple battery and LED setup with the resistor "before" and "after" the LED light. If electrons are flowing from the battery and the resistor is needed to effectively slow down or de-pressurize the electricity to keep the LED light safe, how is it that they can appear after the LED in the circuit? This may seem stupid but I simultaneously get it and don't get it. I get how "they do the same job anywhere in a circuit" may be right but something in my brain thinks that makes no sense. Edit: Ok, looked around and I learned that it doesn't matter because of a basic rule that I guess I took too literally with the water analogy. I'm glad I was able to get to this altered (but correct) way of seeing it now, as opposed to later. *Voltage is equal across the circuit from beginning to end, immediately. Meaning that a resistor anywhere has the same effect across the circuit* So, don't think of this in the sense of electrons bursting out of the source and flowing like a tidal wave across the circuit. That "start here and run to the end" idea isn't exactly right. Think of it in the sense that the moment the circuit is complete it has a set, stable voltage from the beginning and end at essentially the same time BECAUSE of what voltage is/means. In this sense you have to lose or alter the water analogy a bit. This seems like a basic notion but I'm clearly not alone because a google search came back with literally hundreds of discussions about this very topic/question. Haha. It must be a way that some of us interpret the water anlogy as we applied it a bit too literally or strictly.
Thanks for pointing this out. I assumed to protect the LED it would have to be upstream, like a fuse, but this makes sense, the resistor can act like a valve to control flow either upstream or downstream.

5:54 I tested this and my results are different. If I put 10 ohms on a 9V power source I get burned fingers instead of 9V
Your resistor power rating has to be higher than the power consumption of the resistor.
Then YOU'll become the resistor, you must put the multimeter in your correct pole!
How´s that? Do the same way he did ! The cable must be isolated... Then, before you connect everything to the battery, first connect the resistor with the cable. Ok, now, you can connect the cable points to the battery!!
When you´ll be ready to measure, grab you Multimeter put it in the right measure position,=Voltage,Current or resistence=,
and put the Multimeter terminals on each side of the resistor.
And this is how you will have a read !
PS: In that especific case, you can measure the voltage but also the current. So, you apply a known formula__Ohm´s LAw_
The voltage you already know= 9Volts.
Now you want to know the Current_! SO, OHm´s Law:: Voltage= Restitance * Current__!!!!! To know now the current:::
::::::: Current = Voltage / Resitance::::: So, Volts= 9 volts / Resistance=10 ohm = TOTAL= 0.9 Amper (current).

In the circuit with an led and resistors you calculate the current as if the resistors were connected to 9v directly. Shouldn't it be 6v because the led is dissipating 3v?
and most LEDs dont like 9v, typically 1.9- 3.6v depending upon color. so increasing resistance not only reduces current but voltage
Yes, but that would make the video too complicated, especially since LED voltages vary quite alot depending on type. Ignoring the LED voltage in this case also is an error on the "safe" side, because in reality the LED will get less current than calculated.
Yup. You remove whatever voltage across the resistor that the LED blocks.

thank youuu very much
Great video! Quick question - why is current represented using A? I thought current was represented using I?
An ampere ('A') is the unit used to measure electric current. Current ('I') is a count of the number of electrons flowing through a circuit.
Good explanation sir
Thank you bhai
Respect for you sir
Current=9v/460 ohm=0.0195 amp which is less than .02 amp.
The led will be ok and light up.
Thank you Sir.
