Physics-AC Voltage
NEET Physics AC Voltage MCQ Question
Type: MCQ-fact-Medium-Class 12
What happens to the current and voltage during the decreasing phase of the current in an AC circuit?
A
The voltage is negative and energy is returned to the source.
B
The voltage is positive and energy is absorbed from the source.
C
The current remains constant while voltage decreases.
D
The current becomes positive and energy is returned to the source.
Correct Answer
Option A
Detailed Explanation
During the decreasing phase of the current, the voltage becomes negative, indicating that energy is being returned to the source as the core demagnetizes and the net flux becomes zero.
