Two node method

Lecture



The method of two nodes is a special case of the method of nodal potentials. It is used when the circuit contains only two nodes (parallel connection).

Algorithm:
Positive current directions and voltages between two nodes are arbitrary;
Equation for determining inter-nodal voltage

Two node method

where G - branch conductivity, J - current sources;

Rule: G • E and J are taken with a “+” sign if E and J are directed to a node with high potential;
The currents of the circuit are determined by the generalized Ohm's law.

Example:
