Nodal analysis produces a compact set of equations for the network, which can be solved by hand if small, or can be quickly solved using linear algebra by computer.

Because of the compact system of equations, many circuit simulation programs (e.g. When elements do not have admittance representations, a more general extension of nodal analysis, modified nodal analysis, can be used. Even though the nodes cannot be individually solved, we know that the combined current of these two nodes is zero.

Nodal analysis is a circuit analysis technique that can be applied to any circuit.

The nature of nodal analysis allows you to perform circuit analysis on a circuit that has been generalized (no values, just variables).

Step 2 − The node voltages, V is the voltage from node 2 with respect to ground.

Step 3 − In this case, we will get two nodal equations, since there are two principal nodes, 1 and 2, other than Ground.

The branch currents are written in terms of the circuit node voltages.

As a consequence, each branch constitutive relation must give current as a function of voltage; an admittance representation.

The benefit of nodal analysis allows you to solve a circuit once and place any values for the variables that you want within the equations.

This method is very efficient when trying to find optimal values for circuits because you can adjust values of variables without having to completely resolve the circuit.
