Question

How is the voltage phasor \[V_C\] related in phase to the current?

विकल्प

• Voltage leads the current by \[\dfrac{\pi}{2}\] (90°).

• Voltage is in phase with the current \[(\phi=0^\circ)\].

• Voltage lags the current by \[\dfrac{\pi}{2}\] (90°).

• Current lags the voltage \[(\phi<0)\].

Answer 1

Across a capacitor C, the voltage lags the current by \[\dfrac{\pi}{2}\]. This phase difference is 90°.
