Complex PowerIt is very conceptual and essential to understand. For establishing the expression of complex power, we have to first consider a single phase network that’s voltage and current can be represented in complex form as V.ejα and I.ejβ. Where α and β are angles that voltage vector and current vector subtend with respect to some reference axis respectively. The active power and reactive power can be calculated by finding the product of voltage to conjugate of current.That means,This (α −
