Question

When the frequency of the voltage applied to a series RL circuit is increased, the phase angle

• A. Increases
• B. Decreases
• C. Cannot be determined without values
• D. Remains same

Answer 1

The correct option is A Increases

Phase angle$=\varphi ={\tan }^{-1}\frac{\omega L}{R}$

Hence, on increasing frequency of voltage that is $\omega$, phase angle also increases.

Answer-(A)
