Question

Choose the best definition of dielectric loss.

(a) Absorption of electric energy by dielectric in an AC field

(b) Dissipation of electric energy by dielectric in a static field

(c) Dissipation of heat by dielectric

(d) Product of loss tangent and relative permittivity

The question was asked in homework.

This key question is from Electric Fields in Material Space topic in section Electric Fields in Material Space of Electromagnetic Theory

Answer 1

The correct option is (a) Absorption of electric energy by dielectric in an AC field

Best explanation: In the scenario of an AC field, the absorption of electrical energy by a dielectric material is called as dielectric loss. This will result in dissipation of energy in the form of heat.
