I am really sorry for that. Please tell me where do i post if i have a problem and I'm not able to attempt like i don't even know how to begin solving it. Where should those questions go?

Have you learned about AC circuits?

Have you learned about AC circuits?

Yes...I have understood this question. Would love to hear a new explanation if you have one. Thank you :)

Dunno. We are explicitly forbidden to help if no attempt is made by the poster. It also is useless to give someone an answer that he/she doesn't understand at all (complex numbers, differential equations etc require some previous knowledge from a course or textbook). We can't start at primary school level.
Oh well, Ersbeth was faster.

WHAT have you learned about AC circuits that might be useful herre ? 2. relevant equations !
