Question

2. (a) Define RMS value of an a.c. sinusoidal voltage. Give the relation between the R.M.S. value and peak value of sinusoidal voltage. ​

Answer 1

Answer:

Then the RMS voltage (VRMS) of a sinusoidal waveform is determined by multiplying the peak voltage value by 0.7071, which is the same as one divided by the square root of two ( 1/√2 ). ... Note that multiplying the peak or maximum value by the constant 0.7071, ONLY applies to sinusoidal waveforms.
