Question

An inductive circuit contains resistance of $10 \,\Omega$ and an inductance of $20\, H .$ If an AC voltage of $120\, V$ and frequency $60\, Hz$ is applied to this circuit, the current would be nearly

• A. 0.32 A
• B. 0.016 A
• C. 0.48 A
• D. 0.80 A

Answer 1

Answer: (B)

$i=\frac{V}{\sqrt{R^{2}+\omega^{2} L^{2}}}$
$=\frac{120}{\sqrt{100+4 \pi^{2} \times 60^{2} \times 20^{2}}}=0.016 A$
