Question

Define the peak value and root mean
square value of the Alternating current,
establish the relationship between them
and obtain the expression of root mean
square current​

Answer 1

Answer:

irms = Peak value /√2

The peak value is the highest voltage that the waveform will ever reach, like the peak is the highest point on a mountain. The RMS (Root-Mean-Square) value is the effective value of the total waveform. It is equal to the level of the DC signal that would provide the same average power as the periodic signal.
