Question

What happens to the quality factor when resonant frequency increases?

(a) Increases

(b) Decreases

(c) Remains the same

(d) Becomes zero

I got this question in class test.

This interesting question is from Frequency Variation in a Series RLC Circuit topic in division Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

Correct answer is (a) Increases

To explain I would say: Q=fres/Bandwidth

Quality factor is directly proportional to resonant frequency. So, if resonant frequency increases quality factor increases.
