Question
Physics Question on electrostatic potential and capacitance
A parallel plate capacitor is charged by connecting to a battery. After charging, the battery is disconnected. Which of the following increases, when the plates of the capacitor are moved apart ?
A
Charge
B
Potential
C
Capacitance
D
None of the above.
Answer
Potential
Explanation
Solution
When the plates are moved apart, charge cannot change, but capacitance will decrease. So V = q/C will increase, so the potential difference will increase.
