Rms full form: The root-mean-square (rms) voltage of a

The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (Vrms) is used to characterize the source. It is the square root of the time average of the voltage squared. The value of Vrms is V0 /√2, or, equivalently, 0.707 V0. 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. What is the full form of RMS? The full form of RMS in electrical is Root Mean square. The RMS value is used for measuring AC voltage and current. It helps determine the equivalent value of a varying current or voltage that would produce the same heating effect as a DC circuit. What is Root Mean Square (RMS)? Statistically, the root mean square (RMS) is the square root of the mean square, which is the arithmetic mean of the squares of a group of values. RMS is also called a quadratic mean and is a special case of the generalized mean whose exponent is 2. Root mean square is also defined as a varying function based on an integral of the squares of the values which are instantaneous in a cycle. In other words, the RMS of a group of numbers is the square of the ...
