# Electrical Engineering

The application of the theoretical foundations of electrical engineering for the calculation of electrical circuits, Kirchhoff’s laws, the method of circuit currents, the method of nodal potentials.

## Method of nodal potentials: conclusion of the method

Along with solving electrical circuits according to laws of Kirchhoff and the method of loop currents, the method of nodal potentials is also used. Its use is rational if the number of nodes is greater than the number of independent loops in the circuit.
