4.9 MESH ANALYSIS OF CIRCUITS CONTAINING DEPENDENT SOURCES

Dependent voltage sources do not pose any problems for mesh analysis. Independent voltage sources appear on the right-hand side of mesh equations. However, dependent voltage sources affect the coefficients of mesh current variables on the left-hand side of mesh equations.

The controlling variable of a linear dependent voltage source will be a voltage or a current existing elsewhere in the circuit. However, any voltage or current variable in the circuit can be expressed in terms of mesh current variables. Hence, the dependent voltage source function can be expressed in terms of mesh current variables. Therefore, dependent voltage sources will affect the coefficients of mesh equation, i.e., ...
