Question

relation between root mean square and maximum emf​

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 )

Therefore, the relationship between the peak and the rms value of current in an a.c. circuit is Irms=0.707I0.
