A 44 mH inductor is connected to 220 V, 50 Hz ac supply.

Inductance of inductor, L = 44 mH = 44 × 10−3 H

Supply voltage, V = 220 V

Frequency, ν = 50 Hz

Angular frequency, $\omega=2 \pi v$

Inductive reactance, $X_{\mathrm{L}}=\omega L=2 \pi v L=2 \pi \times 50 \times 44 \times 10^{-3} \Omega$

Rms value of current is given as:

$I=\frac{v}{X_{\mathrm{L}}}$

$=\frac{220}{2 \pi \times 50 \times 44 \times 10^{-3}}=15.92 \mathrm{~A}$

Hence, the rms value of current in the circuit is 15.92 A.
