Web12.2.4 Average Value The average value of an AC current or voltage is the average of all the instantaneous values during one alternation. They are actually DC values. The average value is the amount of voltage that would be indicated by a DC voltmeter if it were connected across the load resistor. WebThe RMS value of a wave shape gives the same DC value required to produce the same heating effect in a resistive circuit. For example it would take 230V DC to produce as much heat from a bar heater, as a 230V AC RMS supply. The peak value of RMS is however much higher than the equivalent DC voltage. RMS = Peak x 0.707.
