Equation 17.3-1 and Eqn. 17.3-3 help us to evolve a procedure for solving an electrical network by determining its node voltages first. First, we consider a network containing two-terminal passive elements and independent current sources only.

The network has to be prepared for nodal analysis first. The preparation required in this case consists of replacing series/parallel combination of similar elements with a single element, wherever such a replacement is possible. In addition, the circuit may have to be transformed into an s-domain equivalent circuit or a phasor equivalent circuit depending on the analysis context. The initial condition sources in the s-domain equivalent circuit have to be in the current source ...
