Question

Obtain the resonant frequency ωr of a series LCR circuit with L = 2.0 H, C = 32 μF and R = 10 Ω. What is the Q-value of this circuit?

Answer 1

Inductance, L = 2.0 H
Capacitance, C = 32 μF = 32 × 10⁻⁶ F
Resistance, R = 10 Ω
Resonant frequency is given by the relation,

Now, Q-value of the circuit is given as:

Hence, the Q-Value of this circuit is 25.
