Expert Answer
- RMS value of an AC current represent the equal amount of power in DC current.
- If there are two circuits, D.C and A.C and both are required to be of the same amount of power (or energy per second) then we would choose the D.C values of current and voltage to be the same as the rms values of current and voltage in the a.c. circuit.
- The below are the voltage and current rms values.
- Here Vo and Io are the peak values of voltage and current respectively.
