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

Click For Summary

Homework Help Overview

The discussion revolves around an RC circuit connected to a 20V AC source, with a specific focus on the voltage across the resistor and the unknown voltage across the capacitor. The subject area is AC circuit analysis.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between the voltages across the resistor and capacitor in an AC circuit, questioning the original poster's understanding and approach to the problem. Some participants inquire about the original poster's prior knowledge of AC circuits and relevant equations.

Discussion Status

The discussion is ongoing, with participants expressing varying degrees of willingness to assist based on the original poster's attempts. There is a recognition of the need for foundational knowledge in AC circuits before progressing further.

Contextual Notes

There are indications that the original poster may not have made a sufficient attempt to solve the problem, leading to some participants questioning the appropriateness of providing help. Additionally, there are constraints regarding the level of assistance that can be offered based on the poster's prior knowledge.

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 !
