RMS stands for Root-Mean-Square of instantaneous current values. The RMS value of alternating current is given by direct current which flows through a resistance. The RMS value of AC is greater than the average value. The RMS value of sine current wave can be determined by the area covered in half-cycle.

What is RMS value in electrical?
The rms value of a sinusoidal voltage (or any time-varying voltage) is equivalent to the value of a dc voltage that causes an equal amount of heat (power dissipation) due to the circuit current flowing through a resistance.
What is RMS value of AC definition?
Root mean square or R.M.S. value of Alternating current is defined as that value of steady current, which would generate the same amount of heat in a given resistance is given time, as is done by A.C. current , when maintained across the same resistance for the same time.
What is RMS value and average value?
RMS value is the amount of heat produced by a resistor when at a time both AC and DC are passed through it. Average value is the area of the one cycle of sinusoidal wave to the time period. However, instantaneous value is the value at a particular instant.
What is the purpose of RMS value?
Root-mean-square (rms) refersto the most common mathematical method of defining the effective voltage or current of an AC wave. To determine rms value, three mathematical operations are carried out onthe function representing the AC waveform: (1) The square of the waveform function (usually a sine wave) is determined.
