The RMS (effective) value of a sine wave of current is 1/√2 , or about 0.707, times the peak value. The RMS value of a sine-wave voltage should be such that the average power is the product of the RMS voltage across and RMS current through the resistance of the circuit, just as P = VI in the equivalent DC circuit.

What is RMS value of sine wave?
As discussed above the RMS value of a sine wave is denoted as Irms=Im√2 or for sinusoidal voltage it is Vrms=Vm√2. Alternating Current or AC. Im and Vm here are the peak value of current and voltage respectively.
What is meant by RMS value?
Root mean square or R.M.S. value of Alternating voltage is defined as that value of steady Potential Difference, which would generate the same amount of heat in a given resistance is given time, as is done by A.C. voltage , when maintained across the same resistance for the same time.
What is RMS in simple terms?
The root mean square (RMS or rms) is defined as the square root of the mean square, i.e. the arithmetic mean of the squares of a given set of numbers.
What does RMS signal tell you?
The square root of the mean of the square. RMS is (to engineers anyway) a meaningful way of calculating the average of values over a period of time. With audio, the signal value (amplitude) is squared, averaged over a period of time, then the square root of the result is calculated.
