Which of the following statements are true? Check all that apply.

A) The electric field between the plates of a parallel-plate capacitor is uniform.

B) A capacitor is a device that stores electric potential energy and electric charge.

C) The capacitance of a capacitor depends upon its structure.

D) A capacitor consists of a single sheet of a conducting material placed in contact with an insulating material.

Answers.

a. The electric field between the plates of a parallel capacitor is uniform

b. A capacitor is a device that stores potential energy and electric charges.

c. The capacitance of a capacitor depends upon its structure.

Explanation

Capacitor is a device that is used to store electric charge. The capacitance that can be stored in a capacitor depend on area of overlap of the plates, dielectric used and distance between the two plates of a parallel capacitor.

From the choices given in the question the one that applies are:

a. The electric field between the plates of a parallel capacitor is uniform

b. A capacitor is a device that stores potential energy and electric charges.

c. The capacitance of a capacitor depends upon its structure.
