Question

The capacitance of a capacitor does not depend on the absolute permittivity of the medium between the plates. (a) True (b) False This question was posed to me in a job interview. Asked question is from Basic Network Concepts topic in portion Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer 1

The correct choice is (b) False To explain I would say: C = Ɛ A d Where d is the distance between the plates, A is the cross-sectional area of the plates and Ɛ is absolute permittivity of the medium between the plates. Hence, the capacitance of a capacitor depends on the absolute permittivity of the medium between the plates.
