A 44 mH inductor is connected to 220 V, 50 Hz ac supply. Determine the rms value of the current in the circuit.

Given data in the question can be listed as, 

Inductance , L = 44mH = 0.044 H

RMS Voltage ,Vrms = 220 V

Frequency, f = 50Hz

Irms = ?

Inductive reactance , 

X_L = ωL = 2πfL = 2x3.14x50x 0.044 = 13.82 ohm

Irms = Vrms / X_L

_{Irms = 220 / 13.82 = 15.92 A}
