WebA periodic sinusoidal voltage is constant and can be defined as V(t) = Vmax*cos (ωt) with a period of T. Then we can calculate the root-mean-square (rms) value of a sinusoidal voltage (V (t)) as: Integrating through with limits taken from 0 to 360 o or “T”, the period gives: Where: Vm is the peak or maximum value of the waveform. WebApr 4, 2024 · Peak voltage, which we designate as VP, is measured from the horizontal axis (at 0 reference height) to the top of the waveform or crest. AC Peak Voltage vs. AC Peak-to-Peak Voltage Keep in mind that AC stands for alternating current, and this also means that the voltage alternates (changes polarity) a set number of times in a given period.
