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.

Now consider the x matrix, the matrix of unknown quantities. The topmost 3 (in general n) elements are simply the node voltages.

The bottom 2 (in general m) elements are the currents associated with the voltage sources.

Nodal analysis writes an equation at each electrical node, requiring that the branch currents incident at a node must sum to zero.

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.For instance, for a resistor, I * G, where G (=1/R) is the admittance (conductance) of the resistor.

Though the node voltage method and loop current method are the most widely taught, another powerful method is modified nodal analysis (MNA).We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services.To learn more or modify/prevent the use of cookies, see our Cookie Policy and Privacy Policy.The rules for modified nodal analysis are given by: Consider the circuit shown below (Step 1 has already been applied) Apply step 2 (currents through the voltage sources with current from positive node to negative node): Apply step 3 (with positive currents out of the node): Apply step 4: Apply step 5: or Now all that is left is to solve the 5x5 set of equations (recall that the nodal analysis method resulted in just 1 equation, though we did some substitutions along the way).Solving the 5x5 equation is difficult by hand, but not so with a computer.
