Question

Calculate the value of capacitor voltage during resonance condition if the value of supply voltage is 20 V and the quality factor is 3.

(a) 60 V

(b) 50 V

(c) 10 V

(d) 30 V

I had been asked this question in final exam.

I would like to ask this question from Regenerative Braking of DC Series Motors in section Braking of DC Motors & Induction Motors of Electric Drives

Answer 1

The correct option is (a) 60 V

Explanation: During the resonance condition XL=Xc. The value of the capacitor voltage is Q×Vs. The power factor of the circuit is one. Vc=20×3=60 V.
