as i knw the power factor is defined as
PF = [I(rms, fundmental)/ I rms ] * cos (alpha)
suppose the alpha = 90 degree wouldn't the PF be 0 based on the above formula.
suppose alpha > 90 degree, wouldn't the PF be negative?
can anyone advise me on the calculations of PF for alpha having angle of 90 degree and beyond.
Thanks
