AC Power is an alternating current electrical energy consumed by the load connected in an electrical circuit, generally measured in horsepower, watts, kilo-watts or kilo-watts-hour. AC single phase amps to kilowatts calculation The power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) divided by 1000: P (kW) = PF × I (A) × V (V) Mathematically, Power factor is the cosine of angle θ between real power and apparent power. The symbol for phase angle is θ (Theta) and which represents the inefficiency of the AC circuit with regards to the total reactive impedance (Z) that opposes the flow of current in the circuit. Single-Phase Calculations Basic electrical theory tells us that for a single-phase system, kW = (V × I × PF) ÷ 1,000. The following table shows the different electrical power formulas in both AC and DC circuits. Single- and three-phase power are both terms describing alternating current (AC) electricity. For the purely inductive circuit, the power factor is zero, because true power equals zero.
