Two node method

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



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:




The compilation of formulas for calculating currents is carried out in accordance with the rules of EMF signs and voltages, when calculating according to the generalized Ohm's law.
