What is the phase relationship between current and voltage in a purely capacitive AC circuit?

A. The current leads the voltage by 90 degrees
B. The voltage leads the current by 90 degrees
C. The current and voltage are in phase
D. The current lags the voltage by 90 degrees

Explanation:

In a purely capacitive circuit, the current leads the voltage by 90 degrees due to the behavior of capacitors in AC circuits.
