ABSTRACT
This chapter presents various new techniques to solve complex circuits or networks. It reviews both Kirchhoff's current and voltage laws to solve complex circuits by generating simultaneous equations in order to determine the various unknown quantities within the circuit. Simultaneous equations are used to represent conditions in which two or more unknown variables are related to each other through an equal number of equations. For relatively straightforward complex circuits with, say, just two or three unknown currents, Kirchhoff's loop analysis method is reasonably straightforward. To solve complex circuit, it is easy to use the network theorems such as superposition theorem which is used to apply logical methods for solving the complex circuit with more than one voltage source. The complex circuits can also be solved by using delta-star/star-delta transformation method and Thevenin's theorem. The chapter also identifies junctions or nodes and loops or meshes in complex circuits.
