WebThe frequency of the voltage is symbolized by f and given by f = 1/T. In terms of ω, f = ω/2π, in hertz. The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (V rms) is used to characterize the source. It is the square root of the time average of the voltage squared. WebThe force is called Electromotive Force (EMF). EMF is measured in voltage. The letters in Ohm's Law show a relationship between voltage, current, and resistance, and at the heart of that relationship is the electron.
