[@tannxra2556]

thanks bro ur vids are really helpful to me and my friends

[@johnHeshmat]

Glad to hear that

[@enokimushroom2669]

19:12 hi sir, for question 32, can you please explain why the answer is D?

[@johnHeshmat]

Transformers only work with and produce alternating currents

[@johnHeshmat]

Also core does not conduct current between coils it only increases strength of magnetic field

[@tamerzaghlol9461]

Hi sir, how do we know the current original direction for q30. Thanks

[@johnHeshmat]

it said in the question that for + pd x is more positive than y that's like saying x is + and y is - . current goes from + to -
P is in the negative part of the graph so current is now from y to x@@tamerzaghlol9461
