A $220\, V$, $50 \,Hz$ $ac$ source is connected to an inductance of $0.2\,H$ and a resistance of $20\, ohm$ in series. What is the current in the circuit.......$A$

A

$10$

B

$5$

C

$33.3$

D

$3.33$

Solution

(d) $i = \frac{{220}}{{\sqrt {{{(20)}^2} + {{(2 \times \pi \times 50 \times 0.2)}^2}} }}$$ = \frac{{220}}{{66}} = 3.33\,A$
