Question

An alternating voltage has peek value 14 . 14 V its rms value is ?​

Answer 1

Answer:

The rms value an AC current is equal to the dc current that delivers the same average power to a resistor as the periodic current. Therefore, the constant current i that produces the same heating effect as AC current of peak value 14A, in a metal wire is :
