Here, b is the number of branches in the circuit and ais is
the number of independent and dependent current sources.
For convenience, define all mesh currents using a clockwise
direction of rotation. Identify the solution vector of mesh
currents I,. This vector contains as many components as the
number of independent mesh currents given by (16). These
components may be in any appropriate order. A mesh current
passing through a current source on the perimeter of the
circuit equals the current in the source, so is not a member of
