Title: 14_2 The Mean Value and the Root-Mean-Square Value
Course: HELM Workbooks 2023-2024 > Section: HELM 14: Applications of Integration 1

Currents and voltages often vary with time and engineers may wish to know the mean value of such a current or voltage over some particular time interval. The mean value of a time-varying function is defined in terms of an integral. An associated quantity is the root-mean-square (r.m.s). For example, the r.m.s. value of a current is used in the calculation of the power dissipated by a resistor.
