NEET Physics AC Voltage MCQ Question
Which of the following statements about AC voltage in a capacitive circuit is correct?
In an AC circuit, a capacitor allows the current to flow continuously without resistance.
A fully charged capacitor in an AC circuit will completely block the current.
The current in an AC circuit with a capacitor oscillates with the same frequency as the voltage source.
The voltage across a capacitor in an AC circuit is always in phase with the current flowing through it.
Correct Answer
Detailed Explanation
In an AC circuit, the current through a capacitor oscillates with the same frequency as the source voltage, though the current leads the voltage by 90 degrees. This reflects the sinusoidal nature of both current and voltage in such circuits.
