Capacitance: Dielectric Material

APPH12-WXYKWQ

An air-gap parallel-plate capacitor is fully charged and left connected to its battery.

When a piece of dielectric material is inserted between the plates, which of the following best describe what happens to the capacitor's capacitance and the amount of charge it stores?

A

Capacitance increases, amount of charge stored increases.

B

Capacitance increases, amount of charge stored decreases.

C

Capacitance decreases, amount of charge stored decreases.

D

Capacitance decreases, amount of charge stored increases.
