In an $A C$ circuit, a resistance $R$ is connected in series with an inductance $L$ . If the phase angle between the voltage and the current is $\frac{π}{4}$ , then the value of the inductive reactance is

Options:

Answer:

Solution:

If the phase angle is $ϕ$ , then

$tanϕ = \frac{X_{L}}{R} \Rightarrow \tan (\frac{π}{4}) = \frac{X_{L}}{R} \Rightarrow X_{L} = R$
