    Exactly in these days everyone wants to teach with technical difficult terms, I don't mind but not everyone understands that way. I remember when I was a kid my teacher expected me to read fast like everyone else, if I didn't was would get yelled at, maybe that's why now as an adult if someone is trying to teach me something I wanna beat their face when I see they get frustrated trying to teach me, in my head iam like give me time iam trying to understand and your standing there getting mad at me because I don't understand fast. 🤨

    Thats because your teacher is not paid to teach exclusively, but to do research which brings in money for the university. Teaching is secondary for most professors, and endowments pay most of tuition, not student fees.

Like you they both had the same clarity of presentation, free of waffle, not bogged down in too much math where it is not neccessary, concise & engaging. Well done!

    Perfect lesson again. I got to test circuit breakers using huge, Frankenstein-like test sets with 6" diameter knobs., analog and digital meters and timers. What a BLAST!! The three basic tests were long time, short time and instantaneous to determine how well the circuit breakers performed under actual load. The first test set was the transformer/controller that we fed with 480 single phase which dropped it down to a very low voltage C clamping large cables to each breaker phase then applied current to each until the breaker tripped. Instantaneous (depending on the test curve of each size, type, brand...) was about 10 times the breaker rating, short time was about 5 and long time was around twice the breaker rating.

    I don’t know why, but watching this video gave me a eureka moment. The reason an inductor can overload when there is LESS voltage is because the inductive reactance is less causing less impedance! And lower impedance means MORE current!!!! Holy shit! And that’s why dimmers aren’t suppose to be used in fans! Because they increase the resistance of the circuit which causes less current and the less current results in LOWER impedance and the lower impedance causes more current! Holy shit I am so happy it clicked!!!! I don’t know why which this specific video man but u are awesome! Im like level 4 nec but this always puzzled me and none of my instructors could make this link for me! Don’t stop what ur doing!

    Good example with ground fault. But I would always give two ground fault examples. One like yours where the fault goes to the ground wire. And another where the ground fault goes to the dirt/earth/water and doesn’t touch the ground wire. Then I would explain that both types will trip gfci. This gets people to think and realize that the gfci device can sense a fault where the ground wire is not involved at all. This way people can understand that gfci works correctly on a circuit that has no earth ground.
