For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero.
For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero.
The difference between peak positive and peak negative values of an A.C. voltage is called as peak-to-peak value.
The r.m.s value of A.C. is equal to 0.707 of max. value.
For a pure sinusoidal waveform the Form Factor will always be equal to 1.11.
