An inductor 200 MH, capacitor 500µf, resistor 10Ω are connected in series with
100V variable frequency ac source. Calculate.
1)Frequency at which power factor of the circuit is unity.
2)Q factor
Given that
L = 200 mH = 200 × 10–3 H
C = 500 µF = 500 × 10–6 F
R = 10Ω
(i) Power factor is unit at the resonance frequency
= 15.92 Hz
(ii)
Q factor
