NEET Physics AC Voltage MCQ Question
Which of the following statements about AC voltage applied to resistors and capacitors is correct?
The current across a resistor in an AC circuit is always in phase with the applied voltage.
A capacitor in an AC circuit completely prevents current from flowing once charged.
The voltage across a capacitor in an AC circuit increases and then decreases with time but does not limit the current.
In a purely resistive AC circuit, the current and voltage are out of phase by 90 degrees.
Correct Answer
Detailed Explanation
In an AC circuit, the current across a resistor is indeed in phase with the applied voltage, as indicated in the summary. In contrast, a capacitor in an AC circuit regulates current but does not completely prevent it from flowing.
