Question

If in an alternating current circuit, capacitance of 30 µF is connected to a supply of 200V,50Hz. Find the current in the circuit.

(a) 1.38 A

(b) 1.89 A

(c) 1.74 A

(d) 0.89 A

The question was posed to me during an interview.

I need to ask this question from Resistance and Capacitance in Series topic in section Single Phase Series Circuits of Basic Electrical Engineering

Answer 1

The correct choice is (a) 1.38 A

Explanation: XC=1/(2πfC)=106.1

I=V/XC=200/106.1=1.89 A.
