What is the steady value of EMF which will produce the same amount of heat in a resistance in a given time as the alternating current EMF does in the same resistance and in the same time called?
Answer & explanation
Correct answer: option 2
The steady value of EMF which will produce the same amount of heat in a resistance in a given time as the alternating current EMF does in the same resistance and in the same time is called RMS EMF.
