ELECTRONIC FORMULAS Ohm's Law Formulas for D-C Circuits. Ohm's Law Formulas for A-C Circuits and Power Factor. In the above formulas 1 is the angle of lead or lag between current and voltage and cos 1 = P/EI = power factor or pf. Note: Active power is the "resistive" power and equals the equivalent heating effect on water.
