Question

An inductive circuit contains a resistance of $10\, \Omega$ and an inductance of $2.0\, H$. If an $AC$ voltage of $120\, V$ and frequency of $60\, Hz$ is applied to this circuit, the current in the circuit would be nearly

• A. $0.32\,A$
• B. $0.16\,A$
• C. $0.43\,A$
• D. $0.80\,A$

Answer 1

Answer: (B)

$0.16\,A$

Answer 2

Impedence $Z=\sqrt{R^{2}+X_{L}^{2}}$
$=\sqrt{10^{2}+(2 \pi \times 60 \times 2)^{2}}$
$=0.016\, A$
$\therefore$ Curren $i=\frac{120}{753.7}=0.159 \,A$
