4.7 MESH CURRENT ANALYSIS
WITH DEPENDENT SOURCES
When a circuit contains a dependent source the controlling current or voltage of that
dependent source must be expressed as a function of the mesh currents.
It is then a simple matter to express the controlled current or voltage as a function of the mesh
currents. The mesh equations can then be obtained by applying Kirchhoff s voltage law to the
meshes of the circuit.
