Form Factor

Definition: The ratio of the root mean square value to the average value of an alternating quantity (current or voltage) is called Form Factor. The average of all the instantaneous values of current and voltage over one complete cycle is known as the average value of the alternating quantities. Mathematically, it is expressed as: Ir.m.s …
