2.3 NODAL ANALYSIS
Nodal analysis is a technique used to fi nd
the voltage at various nodes of an electric
circuit. This can be done by using KCL at
various nodes. The application of KCL at
each node will give the node equation.
A node is a point in an electric circuit at
which current divides. For example, con-
sider the circuit shown in Figure 2.25.
In this circuit, points A and D are not
nodes because current is not getting divided here. However, points B and C are nodes because
at these points current is dividing. ...
