Question

Which capacitors relatively costly?

(a) Electrolyte capacitor

(b) Mica capacitor

(c) Air capacitor

(d) Glass capacitor

I have been asked this question in an online quiz.

My question is taken from Types of Capacitor and Capacitance in division Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

The correct answer is (b) Mica capacitor

To explain I would say: Mica capacitors are relatively expensive because it consists either of alternate layers of mica and metal foil clamped tightly together, or of thin films of silver on the two sides of a mica sheet. Silver is an expensive metal, hence mica capacitors are expensive.
