alleryThe rms current equals the dc current that would produce the same:
APeak voltage
BPhase angle
CTime period
DHeating effect
Answer & Solution
Correct answer: D. Heating effect
1. The rms value is defined to make ac and dc comparable.
2. The comparison is made through the power dissipated.
3. It is the equivalent dc current giving the same heating.
4. So the answer is heating effect.
