Alternating Current

Question:

In an inductive circuit, the inductance is 20 mH and the voltage supplied is V = 44 Sin 60\(\pi \)t. Calculate the RMS current through the circuit.

Options:

26 A

37 A

85 A

105 A

Correct Answer:

26 A

Explanation:

Ipeak = Vpeak/wL = \(\frac{44 V}{20mH * 60}\)

        = 36.67 A 

Irms = 0.71 Ipeak = 0.71 x 36.67 A

       = 26 A
