WebNov 19, 2007 · The RMS value is the equivalent AC voltage or current that generates the same power of a DC voltage or current value. When you squared (to 2nd power) the negative samples/values of the waveform, you turn them into positive values that are added to the positive squared samples. WebThe RMS value is the effective value of a varying voltage or current. It is the equivalent steady DC value which gives the same effect. For example a lamp connected to a 6V RMS AC supply will light with the same brightness when connected to a steady 6V DC supply. However, the lamp will be dimmer if connected to a 6V peak AC supply because the RMS …
