Homework Statement
When the voltage across the two plates of a capacitor is increased then:
*a. the charge will increase
b. the charge will decrease
c. the capacitance will increase
d. the capacitance will decrease
Homework Equations
CV=Q
The Attempt at a Solution
I answered that the capacitance will decrease instead of the charge increasing because if the voltage is not constant ie not connected to a voltage source, the charge doesn't change but the capacitance does.
