RC Circuit: 20V AC Source, 12V Voltage Across R, What about C?

AI Thread Summary
A 50Hz AC source of 20V is applied across a resistor (R) and capacitor (C), with a measured voltage of 12V across R. The discussion revolves around determining the voltage across C, emphasizing the need for foundational knowledge in AC circuits to solve the problem. Participants highlight the importance of making an attempt before seeking help, as understanding the underlying concepts is crucial. The conversation also stresses the necessity of relevant equations and previous learning to approach such circuit problems effectively. Overall, the thread underscores the balance between seeking assistance and demonstrating prior effort in learning.

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?

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 !

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
