Question

A inductance of 0.2 henry is connected to 220V and 50Hz supply. Find the current?

Answer 1

Answer:

Current is 34.55 A

Explanation:

Inductance L = 0.2 H

Vrms = 220 V ,

v = 50 Hz

$I_{rms}=\frac{V_{rms}}{X_{L}}$

here

$X_{L}=2\pi vL\\X_{L}=2\pi\times 50\times 0.2\\X_{L}=20\pi$

Current is

$I_{}rms=\frac{220}{20\pi } \\I_{}rms=11\pi \\I_{}rms=34.55 A$
