Question

If a large amount of voltage is applied to a capacitor, what is the current that flows through it?

(a) Displacement current

(b) Conduction current

(c) Both conduction and displacement current

(d) Neither conduction nor displacement current

The question was posed to me by my college professor while I was bunking the class.

This key question is from Leakage and Conduction Currents in Capacitors topic in section Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

Right choice is (b) Conduction current

For explanation I would say: When a large amount of voltage is applied between the plates of a capacitor, the dielectric between the plates does not behave as an insulator anymore and starts conducting and conduction currents flow through it.
