Steps to determine the mesh
 currents:
 
 1.Assign mesh currents i1,
 i2, …, in to the           
 n
 meshes. 
 2.
 2.Apply KCL to each of the n meshes. Use Ohm’s law to express the
 voltages in terms of the mesh currents. 
 3.
 3.Solve the resulting n simultaneous
 equations   to get the mesh currents.
