What is the RMS voltage of the source?
What is the RMS voltage of the source? The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (Vrms) is used to characterize the source. It is the square root of the time average of the voltage squared. The value of Vrms is V0/Square root of√2, or, equivalently, 0.707V0. Why we use RMS voltage? […]
