Question

The charge build up in the capacitor is due to which quantity?

(a) Conduction current

(b) Displacement current

(c) Convection current

(d) Direct current

This question was posed to me in an internship interview.

Question is from Maxwell Law in section Magnetostics of Electromagnetic Theory

Answer 1

Right answer is (b) Displacement current

To explain I would say: The charge in the capacitor is due to displacement current. It is the current in the presence of the dielectric placed between two parallel metal plates.
