Capacitance: (multiple choice)

  • #1
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???

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.
