RL and RC Series Circuits

In an a.c. circuit, a resistance ' $R$ ' is connected in series with an inductance ' $L$ '. If phase angle between voltage and current is $45^\circ$ , the value of inductive reactance will be $(\tan 45^\circ = 1)$

Show answer and solution

Answer: (a)

For series RL: $\tan\phi = \frac{X_L}{R}$ .
$\tan 45^\circ = 1 \Rightarrow X_L = R$
So the answer is (a) R.
