4.8 MESH ANALYSIS OF CIRCUITS WITH INDEPENDENT CURRENT SOURCES
An independent current source that appears in parallel with a resistor can be converted into an independent voltage source in series with a resistor by applying source transformation theorem. This measure will reduce the number of meshes in the circuit by one and increase the number of nodes in the circuit by one. Such current sources in a circuit do not pose any special problem for the mesh analysis procedure.
An independent current source may also appear in series with another element. Such a current source cannot be converted into an equivalent voltage source. This kind of current source will impose constraints on the mesh current variables in the circuit.
An irreducible independent ...
