Univ. of Ontario Institute of Technology Faculty of Engineering and Applied Science ' \$ % Resistive Network Analysis Network Analysis: Determining the unknown branch currents and node voltages. There are diﬀerent methods for circuit analysis including Nodal analysis and Mesh analysis. In resistive networks, these methods provide us with a minimum number of linear equations of the circuit unknown variables. Electric Circuits (ENGR2790U) 77 of 310

Univ. of Ontario Institute of Technology Faculty of Engineering and Applied Science ' \$ % Nodal Analysis In this method, the voltage of each nodes is deﬁned as an independent variable. One node is selected as the reference node and the voltages of other nodes are referenced to this node. Each branch current is written in terms of the voltage of one or more node voltages. Then KCL is applied at each node, Electric Circuits (ENGR2790U) 78 of 310

Univ. of Ontario Institute of Technology Faculty of Engineering and Applied Science ' \$ % Mesh Analysis In this method, the current of each mesh is deﬁned as an independent variable. All branch voltages and currents may subsequently be obtained from mesh currents. To be consistent, we assume the directions of all mesh currents to be clockwise.
