RMS value of alternating current is defined as the value of the steady current, which when passed through a resistor for a given time, will generate the same amount of heat as generated by an alternating current when passed through the same resistor for the same time.
RMS value is also known as the effective value.
Effective value or RMS value = \({V_m\over \sqrt{2}}\)
where, Vm = Peak value
Calculation
Given, Vm = 388 V
Effective value = \({388\over \sqrt{2}}\) = 275 V
