Different Methods for Circuit Analysis

Fundamental electrical laws, circuit parameters, and resistive circuits with series-parallel and delta-wye have already been discussed. Additional analytical methods have been developed to analyze practical electrical circuits with more than one source. These methods include mesh analysis and node-voltage analysis, also known as nodal analysis. Kirchhoff’s Voltage Law (KVL) is used in the mesh analysis, while Kirchhoff’s Current Law (KCL) is used in the nodal analysis. In these analytical methods, Cramer’s rule appears to be a handy tool that helps solve the system of linear equations after the application of Kirchhoff’s laws in an electrical circuit. A node is a junction point where more than two elements are met. Upon introducing Cramer’s rule, this chapter presents the theoretical foundations of supermesh, supernode, mesh and nodal analysis with dependent and independent sources.
