Complex power units
WebMar 19, 2016 · The conjugate of the current is used to calculate the correct phase difference between the voltage phasor and the current phasor. Power factor is pf = cos (a-b) where … WebThis leads to the generalized concept of complex power. The complex power, S, is defined as S=P+jQ where the real part P is identical to average power and is expressed in watts, the imaginary part Q is known as reactive power expressed in VARs (volt-amperes reactive), and the complex power S has units of VA (volt-amperes).
