The r.m.s. value is the parameter which relates alternating to direct current. The r.m.s. value of an alternating current represents the direct current value that causes the same thermal effects in the same period of time. For example, a direct current of Figure 2 Periodic waveform Figure 3 R.m.s. value (value of the equivalent direct current)
