Question

Which, among the following, is the odd one out?

(a) Ceramic capacitor

(b) Electrolyte capacitor

(c) Tuning capacitor

(d) Paper capacitor

I have been asked this question during an interview.

My doubt stems from Types of Capacitor and Capacitance topic in division Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

Right option is (c) Tuning capacitor

Easy explanation: Ceramic capacitor, electrolyte capacitor and paper capacitor are fixed capacitors whereas tuning capacitors is a variable capacitor, hence it is the odd one out.
