The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

Complex Power: The Sum of the Individual Real and Reactive Powers

The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
