E)does not change the capacitance of the capacitor.

Question

Quizplus · Accepted Answer

Doubling the potential difference across a capacitor does not change the capacitance of the capacitor. The capacitance of a capacitor only depends on its geometry and the dielectric properties of the material between its plates. However, the charge stored on the capacitor is directly proportional to the potential difference, so doubling the potential difference will double the charge stored on the capacitor.
