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

Correct Answer: 90 degrees

Step 1: Understand what a purely capacitive AC circuit is. It means the circuit only has a capacitor and no resistors or inductors.
Step 2: Know that in AC circuits, voltage and current can be out of sync, which is called phase difference.
Step 3: In a purely capacitive circuit, the current flows before the voltage reaches its peak.
Step 4: The current reaches its maximum value 90 degrees (or a quarter of a cycle) before the voltage does.
Step 5: Therefore, we say the current leads the voltage by 90 degrees.
