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 \(\frac{A}{d}\)

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.
