Mesh current method

Mesh current method is one of basic methods for solving electrical circuits. Mesh current method is one of method used for electrical network analysis. Mesh current method is based on Kirchhoff’s voltage law. It means that this mesh current method sees only voltage sources. If an electrical circuit contains a current source then it has to be to transformed into virtual voltage source.
