Question

An inductor of inductance, $L=5\text{H}$ is connected to an AC source having voltage, $V=10\sin (10t+\frac{\pi }{6})$. Find the inductive reactance.

• A. $20\Omega$
• B. $30\Omega$
• C. $70\Omega$
• D. $50\Omega$

Answer 1

The correct option is D $50\Omega$

Given:
Inductance, $L=5\text{H}$
Voltage, $V=10\sin (10t+\frac{\pi }{6})$

So, inductive reactance,

$X_L=\omega L=10\times 5=50\Omega$

Hence, option $\left(C\right)$ is the correct answer.
