AC voltage source and resistor

Learn Vp - volt peak Vpp - volt peak-peak Vrms - volt root mean square Vavg - volt average f - frequency t - time Formulas: Vpp = 2 * Vp Vrms = .707 * Vp Vavg = .637 * Vp Note: Vrms is called the effective or heating value of alternating current, is equivalent to a DC voltage that would provide the same amount of heat generation in a resistor as the AC voltage would if applied to that same resistor.
