Q. A coil having an inductance of $\frac{1}{π} H$ is connected in series with a resistance of $300$ $Ω.$ If $20 V, 200 Hz A C$ source is impressed across the combinations. The phase angle between voltage and current is :

$tan^{- 1} \frac{4}{3}$

$tan^{- 1} \frac{3}{4}$

$tan^{- 1} \frac{5}{4}$

$tan^{- 1} \frac{4}{5}$

Correct answer is (a) $tan^{- 1} \frac{4}{3}$
