Question

The Q-meter works on the principle of

• A. mutual inductance
• B. self inductance
• C. series resonance
• D. parallel resonance

Answer 1

The correct option is C series resonance

$Q=\frac{{\omega }_{0}L}{R}$
Where ${\omega }_0$ is the resonant angular frequency, L is the inductance and R is the effective resistance of the coil.
The principle of working of Q-meter is based upon series resonance of R,L,C circuit.
