In a.c. circuits power consumed is

WebPower Factor (PF) in AC Circuit. The power factor is the factor or ratio by which apparent power is multiplied to obtain the true power, or the actual power being consumed. For all electrical power work with sinusoidal waveforms: P ower F actor =cosθ =R/Z P o w e r F a c t o r = cos θ = R / Z. WebAs a rule, true power is a function of a circuit’s dissipative elements, usually resistances (R). Reactive power is a function of a circuit’s reactance (X). Apparent power is a function of a circuit’s total impedance (Z). Since we’re dealing with scalar quantities for power calculation, any complex starting quantities such as voltage ...
