WebJan 29, 2014 · The root mean square voltage or current are the DC equivalent voltage and current that will produce the same power dissipation over time. If the average power dissipation is 1 / 2 W, then such a power dissipation can be steadily produced by 2 / 2 VDC multiplied by 2 / 2 A DC. WebIf this is meant as a method of measuring the rms value of a mains voltage then the accuracy of the result is really not great. This method relies on the quantity being sinusoidal and mains is typically quite distorted and if measured on the secondary of the average small power transformer it can have far worse distortion. laptop short keys windows 10
