Which one of the following is correct?
Correct answer: A. V0=1.414 Vrms
- A. V0=1.414 Vrms
- B. V0=10.10Vrms
- C. V0=10.70 Vrms
- D. Both A and B
Explanation
This statement is correct. V0 represents the peak value of an alternating voltage, while Vrms represents the root mean square (RMS) value of that voltage. The relationship between the peak value and RMS value in an ideal sinusoidal waveform is V0 = 1.414 Vrms. This is a fundamental relationship in A.C. circuit analysis.Vrms=0.707V0So V0=1/0.707 Vrms=1.414 Vrms

About Phase of Alternating Current
Phase describes the position of an alternating voltage or current within its cycle and the phase difference between two sinusoidal quantities. The topic covers in phase signals, phase angle and lead or lag in resistive, inductive and capacitive circuits, rather than the amplitude or frequency of the supply.
