thers allot of ways to add up the potentials to zero and i got overwhelmed by all the ways... and chose a method which is this and its so simple ... thank you sir..🤜🤛
it surprises me how differently teaching goes from teacher to teacher. My teacher in high school would send me away to the moon with a swift strike if I said voltage at some point. While I'm not sure whether it's correct or not, I was taught that voltage can only be measured between two points and voltage at some point makes no sense. It's difference in potential between two points, so what's the difference if we only have one point?. It still works, V_a is just what I'd call voltage between A and C. All methods still work it's just how described it is. Same with voltage at B. As per what I was taught voltage provided by the battery spreads according to resistances across the rest of the circuit, so instead of saying voltage dropped on that resistor, I'd say voltage across that resistor is this this and that. It changes nothing in calculations but still it's fun to see different ways of explaining and teaching the same things.
I wish the video had been two minutes longer, so he could demonstrate how the voltage drops to zero if there is just one resistance in the circuit, but the voltage gets divided between multiple resistances, in direct proportion to the values of each of the resistances (using each resistor's value in relationship to the total resistance in the circuit), which effectively makes the multiple resistors a simple voltage divider.
The best Physics teacher in the World !!!
Lets appreciate him because he is writing from behind😊
Nicely explained😊. Student from India...✌🇮🇳

does this apply if there are no resistors in the circuit?
Excellent class sir, please make a video on 2 nd law with more than one branches or parallel loops
Working on it.

Dr. A
@@yoprofmatt Thank you sir

I agree with you and I likely got a little sloppy with the verbiage. It happens.

Did you watch the video? He did that....first thing.
Great discussion. Mr. MaskedMarvyl let me know if there is still an outstanding question.

thank you!
You're welcome!

thank u!!
:thumbs-up:
Awesome, thanks much.

Um, how do you spell Kirchhoff? Two h's or one, that is the question? LOL. No big deal. Just having fun. Great lecture.
