The charge stored on a capacitor:
The capacitor is charged to Q = CV = C(20)
The capacitance remains unchanged. When the capacitor is disconnected,
A parallel-plate capacitor is charged by a 20.0V battery, then the battery is removed.
a. What is the potential difference between the plates after the battery is disconnected?
b. What is the potential difference between the plates after a sheet of Teflon is inserted between them?
