Question

The flow of electrons in dielectric is due to _________

(a) Conduction

(b) Potential difference

(c) Breakdown

(d) Resistance

I have been asked this question in final exam.

I'm obligated to ask this question of Leakage and Conduction Currents in Capacitors topic in chapter Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

The correct option is (c) Breakdown

The explanation is: There is, under normal circumstance, no flow of electrons in a dielectric since a dielectric is basically an insulator. Hence, there is a flow of electrons in a dielectric only at breakdown voltage.
