Question

The peak value of ac voltage on a 220 V mains is
(a) 200√2 V
(b) 230√2 V
(c) 220√2 V
(d) 240√2 V

Answer 1

Answer:

• Peak Value = √2*RMS Value of a sinusoidal waveform. ... hence, for 220v AC, peak value will be 220×√2 which is 311.1v approx

Answer 2

The voltage given is the rms voltage = 220 Volts

The relation between the rms voltage and the peak voltage is given by:

$Peak \ Voltage = V_{rms} \sqrt{2}$

Hence,

The peak value of the A.C. voltage on a 220 Volts main is

$Peak \ Voltage = 220 \sqrt{2} \ Volts$

Thus the peak value of the voltage is 220√2 Volts.

Hence, the correct option of the question is an option (c) 220√2 V.
