(RMS value)

*n*) of values of a quantity (*x*_{1},*x*_{2},*x*_{3}…) equal to the square root of the sum of the squares of the values divided by *n*, i.e. RMS value = [√(*x*_{1}^{2} + *x*_{2}^{2} + *x*_{3}^{2}…/*n*]

RMS value = [√(*x*_{1}^{2} + *x*_{2}^{2} + *x*_{3}^{2}…/*n*]

**effective value**, i.e. the value of the equivalent direct current that would produce the same power dissipation in a given resistor. For a sinusoidal current this is equal to *I*_{m}/√2, where *I*_{m} is the maximum value of the current.
