Mesh Current Analysis Methods with a Current Source
CASE
1. A current source appears on the
periphery of only one mesh, n.
2. A current source is common to two meshes.
METHOD
Equate the mesh current in to the current source current, accounting for the
A. Assume a voltage vab across the terminals of the current source, write the
direction of the current source.
k v l equations for the two meshes, and add them to eliminate vab,
or,
B. create a supermesh as the periphery of the two meshes and write one KVL
equation around the periphery of the supermesh. In addition, write the
constraining equation for the two mesh currents in terms of the current
source.
