Question

A 220v 60hz of alternating current is connected to an inductance of 3.5h what is the current passing through the inductor

Answer 1

Solution.

$V=220V;$

$f=60Hz;$

$L=3.5H;$

$I-?;$

$I=\dfrac{V}{X_L};$

$X_L=2\pi f L;$

$X_L=2\sdot3.14\sdot60\sdot3.5=1318.8\Omega;$

$I=\dfrac{220}{1318.8}=0.167A;$

Answer: $I=0.167A.$
