alleryIn a purely resistive ac circuit, the voltage and the current are:
AIn phase
BIn parts
CIn pairs
DIn panels
Answer & Solution
Correct answer: A. In phase
1. A resistor does not store energy in a field.
2. So nothing delays the current behind the voltage.
3. Clearly, the voltage and current are in phase with each other.
4. So the answer is in phase.
