The plot of electric current as a function of time for an alternating current is a sinusoidal curve.The average value of an ordinary alternating current is zero.The power dissipated in a resistance is proportional to the square of the current.Theeffective currentorrms currentis obtained by squaring the current, averaging this value over time, and taking the square root of the result.The effective current Ieffis 0.707 times the peak current Ipeak.
