ABSTRACT
This chapter describes the specific and useful tools which adds or subtracts two or more phasor that lie at various angles, other than right-angles. As these phasors form simple right-angled triangles, then it is needed to apply either Pythagoras's theorem or one or other of the sine, cosine, or tangent ratios in order to solve them. Two or more phasors can be added first by resolving each of the phasors into their horizontal and vertical components, then adding their corresponding horizontal components and their vertical components together and finally, finding the resultant phasor by vectorially adding the new horizontal and vertical components. The horizontal and vertical components of a current phasor are actually exist as a mathematical model. The chapter also deals with the series and parallel AC circuits that enable to add or subtract phasors which do not lie at right-angles to each other.
