How Does Changing the Battery Voltage Affect the Charge on a Capacitor?

Click For Summary

Homework Help Overview

The discussion revolves around the effect of changing battery voltage on the charge of a capacitor, specifically comparing a 6.0 V battery to a 12.0 V battery. Participants are exploring the relationship between voltage and charge in the context of capacitors.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are discussing the relationship defined by the equation Q=CV and questioning how polarity affects the charge. There is also exploration of assumptions that may influence the outcome.

Discussion Status

Some participants suggest that the charge increases with higher voltage, while others are considering the implications of assumptions and the context of the problem. There is no explicit consensus, but various interpretations are being explored.

Contextual Notes

Participants note that several assumptions may need to be clarified, and there is uncertainty regarding whether the problem is part of a larger context that could affect the interpretation.

A capacitor is first connected to a 6.0 V battery and then disconnected and connected to a 12.0 V battery. How does the charge on one of its plates change: (a) It increases, (b) it decreases, or (c) it 1stays the same?








(c) (because the charge on the plate is
depending upon the area of the surface of the plate)


Right?? Not right?
 
Physics news on Phys.org
Q=CV
but one thing is not clear, because polarity matters
 
Now I think it's A) increases...Is this right
 
several assumptions would have to be made, but A) seems the most logical for this question... unless it is part of a bigger problem which tells you more about the setup.
