The capacitance of a parallel plate capacitor:
The charge stored in a capacitor:
The capacitor is charged to V = 17 V.
V = Q/C = 17 V
The potential difference will change if the charge, Q, or the capacitance, C, are changed.
A parallel-plate capacitor is charged by a 17.0 V battery, then the battery is removed. What is the potential difference between the plates after the battery is disconnected? What is the potential difference between the plates after a sheet of Teflon is inserted between them?
