Question

The phase difference between flowing current and applied voltage in alternating circuit containing pure capacitor is -

• A. 0
• B. 1
• C. \( \frac{\pi}{2} \)
• D. \( -\frac{\pi}{2} \)

Hint:

In a purely capacitive circuit, current leads voltage by \( \frac{\pi}{2} \).

Answer 1

The Correct Option is C

In an alternating circuit with a pure capacitor, the current leads the voltage by \( \frac{\pi}{2} \). Hence, the phase difference is \( \frac{\pi}{2} \).
