The value of the current through an inductance of $1H$ and of negligible resistance, when connected through an $ac$ source of $200 \,V$ and $50 \,Hz$ is

A

$0.637\, A$

B

$1.637\, A$

C

$2.637\,A$

D

$3.637 \,A$

Solution

(a) $i = \frac{V}{{{X_L}}} = \frac{{200}}{{\omega L}} = \frac{{200}}{{2\pi \times 50 \times 1}} = 0.637\,A$
