Above Figure shows the voltage waveform. The equation of this wave with point O as the reference is given by ;
So we derived the value of v in normal phase. When we pass that current in A.C. circuit, it goes through phase change.
This equation is valid when time is measured from the instant the voltage is zero i.e. point O. Since the time is measured from the positive maximum value (point A in figure ), the above equation is modified to:
Let the value of voltage become 141.4 volts t second after passing through the maximum positive value. Then,
Let the value of voltage become 141.4 volts t second after passing through the maximum positive value. Then,

A sinusoidal voltage of50Hzhas a maximum value of200√2volts. At ...
Vrms = Vmax / √2
Vrms = 200 / √2
Vrms ≈ 141.42 V
Therefore, the root mean square (RMS) value of the sinusoidal voltage with a maximum value of 200 V and frequency of 50 Hz is approximately 141.42 V.
Vrms = 200 / √2
Vrms ≈ 141.42 V
Therefore, the root mean square (RMS) value of the sinusoidal voltage with a maximum value of 200 V and frequency of 50 Hz is approximately 141.42 V.
