Question

Which description gives the working principle of a parallel plate capacitor?

Options

• Two conducting plates connected without a separation release charge without a potential difference

• Two dielectric plates separated by a conductor store charge only when there is no applied potential difference

• Two conducting plates separated by a dielectric or vacuum store electric charge when a potential difference is applied across them

• One conducting plate separated from a vacuum stores charge without an electric field

Answer 1

A parallel plate capacitor consists of two conducting plates separated by a dielectric or vacuum. It stores electric charge when a potential difference is applied across the plates.
