The magnitude of the charge on the plates of an isolated parallel plate capacitor is doubled. Which one of the following statements is true concerning the capacitance of this parallel-plate system?

Question

Quizplus · Accepted Answer

The capacitance of a parallel-plate capacitor depends only on the geometry of the plates, the distance between them, and the permittivity of the medium between them. Since none of these factors have changed, the capacitance remains unchanged. Doubling the charge on the plates will increase the electric field between the plates, but this does not affect the capacitance.
