Electricity (charge on capacitor in circuit)

Click For Summary

Homework Help Overview

The discussion revolves around a circuit involving a capacitor and a battery with internal resistance. Participants are exploring how to determine the charge on the capacitor plates and the application of Kirchhoff's laws in this context.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Some participants express uncertainty about how to start solving the problem and question the application of Kirchhoff's laws to the capacitor. Others note the steady state of the circuit and inquire about the conditions under which current flows through the capacitor.

Discussion Status

The discussion is ongoing, with participants seeking clarification on fundamental concepts and the rules of the forum. There is a focus on understanding the principles involved rather than arriving at a solution.

Contextual Notes

Participants reference the forum rules regarding homework help, indicating that direct solutions are not permitted. There is also a mention of the circuit being in a steady state, which may influence the behavior of the capacitor.

The problem supposes that the circuit has been connected for a long time, so it is in steady state.
Connecting a capacitor to a voltage source, what drives current through the capacitor? If the voltage across the capacitor is equal to the voltage of the source, does current flow through the capacitor?

For both of Kirchhoff's laws it doesn't matter at all if you use a resistor, a capacitor or anything.
