RMS (Root Mean Square) Value of AC and Alternating EMF
AC can be defined in terms of the heat produced in a resistor due to motion of charges. The effective value (I r m s or I e f f ) of the AC is defined as the value of that direct current which produces the heat at the same rate as the alternating current in a given resistor. The AC is represented a..
