NEET Physics AC Voltage MCQ Question
In an AC circuit, what property is used to define the AC ampere in relation to Joule heating?
It produces the same average heating effect as DC current.
It always flows in one direction.
It has a constant value regardless of frequency.
It is independent of the resistance in the circuit.
Correct Answer
Detailed Explanation
The AC ampere is defined in terms of Joule heating, meaning it produces the same average heating effect as one ampere of DC current under the same conditions.
