Detailed Solution
Download Solution PDFPower in an AC circuit
The power in an AC circuit is the combination of average and reactive power.
The phasor sum of average and reactive power gives apparent power.
S = P + jQ
where, S = Apparent power
P = Average power
Q = Reactive power
Power Triangle
The apparent power is given by:
S = Vrms × Irms
The average or active power is given by:
P = S cos ϕ
P = Vrms × Irms cos θ
The reactive power is given by:
Q = S sin ϕ
Q = Vrms × Irms sin θ
