RMS value or Root Mean Square value is defined as the steady value of an alernating waveform. The RMS value makes it more easy to compare an alternating waveform with the steady waveform.

RMS value means root mean square value. It is 0.707 times peak value of voltage or current. The ammeter and voltmeter records this rms value. RMS value for sine wave is more than average value. RMS value is also called effective value.

RMS value of AC is given by DC which is flowing through a resistance for a given time and producing same amount of heat as produce by AC when AC is flowing through the same resistance for same time.

RMS value of AC is given by DC which is flowing through a resistance for a given time and producing same amount of heat as produce by AC when AC is flowing through the same resistance for same time.
