Nodel Analysis Notes

Nodal analysis provides a general procedure for analysing circuits using node voltages as the circuit variables. Choosing node voltages instead of element
voltages £ circuit variables is convenient and reduces the number of equations one must solve simultaneously.

In nodal analysis, we are interested in finding the node voltages. Given a circuit with n nodes without voltage sources, the nodal analysis of the circuit involves
taking the following procedure:

1. Assume the voltages of the different independent nodes.
2. Write the equations for each mode as per Kirchhoffs current law.
3. Solve the above equations to get the node voltages.
4. Calculate the branch currents from the values of node voltages.
