alleryThe household line voltage of 220 V is which kind of value?
AA sum value
BAn rms value
CA peak value
DA mean value
Answer & Solution
Correct answer: B. An rms value
1. Supply voltages are quoted in one standard way.
2. The peak of the household supply is higher than 220 V.
3. The quoted 220 V is an rms value.
4. So the answer is an rms value.
