Meaning of circuit analysis

The technique by which one can establish a variable (i.e., either a voltage or a current) of a circuit is termed as analysis. A ‘mesh’ is any closed path in a given circuit which does not have any element (or branch) within it. A mesh has the properties that (a) every node in the closed path is exactly created with two branches (b) no other branches are surrounded by the closed path. The meshes are considered as a resembling window partitions. On the other hand, ‘loop’ is too a closed path though inside the closed path there might be one or more than one elements or branches.
