# Problems solving in electrical engineeringâ€” equivalent circuit for the constant-voltage generator method and equivalent current source method

It is known that **the method of the equivalent generator** of the EMF source or current source can simplify the analysis and calculation of circuits in cases where it is necessary to determine
the parameter (current, voltage or power) of only one branch.

Below there are the equivalent circuits for equivalent current source and a source voltage (EMF). It should be taken into account that for the load these circuits are equal as produce the same current I and voltage U.
