Physics 43 Magnetic Forces on Moving Charges (26 of 26) The Direct Current Motor

In this video I will find Emf=? P(provided)=? P(consumed)=? P(mechanical delivered)=? E=? Back Emf=? and what happens if the motor jams of a DC motor in a series circuit.

Thanks you for Everything I passed the exam thanks to you.

why is there a back EMF?
is it due to the induced electric field when the motor is moving?

You can make playlists on DC machines, synchronous machines, induction motors. This is one of the harder electrical/electronics topic. There's only one Indian channel making full playlists on each one, but no one can finish it because it gets very confusing quickly and it's lengthy, like 80-90 20mins+ videos for each playlist.

There are many causal relationships in the AC/DC machines, like feedback stuff looping back and forth that kills brain cells. One of the easier feedback reaction would be the back emf u explained, but as we go deeper it gets crazy. I'd rather study quantum physics than that thing.

If you make playlists on it, I'm sure every electrical/electronics majors will come to u and maybe I can restudy the whole subject again :)

wouldn't the efficiency be equal to [power consumed/ power provided] since 100W is what is actually being used by the motor? i'm not sure.... it's just a but amazing explanation otherwise
