MESH- a loop which does not contain any other loop.

            Kirchhoff’s Voltage Law is the basis of mesh analysis. Like nodal analysis, mesh analysis is also used in analyzing AC circuits. It also provides another general procedure for analyzing circuits using mesh currents as the circuit variables. Using mesh currents as circuit variables is more convenient than using element currents because through this, it lessens the number of equations to be solved. Keep in mind that mesh analysis is only applicable to a planar circuit that’s why it is not that general as the nodal analysis.

            There are also circuits containing supermesh which doesn't have current of its own and two meshes shares in one current source.

            For further understanding of MESH analysis, see sample problem below on how to get equations from a given circuit.

                     EQUATION:

             I've learned that in mesh analysis, we must first assign mesh currents in a given circuit but it is also necessary to apply some strategies that could simplify the circuit to lessen the number of mesh currents and to come out in a few number of equations. There were also some circuits that fit the case 1 in which the current source existing only in one mesh is already the current of that mesh. For me, mesh analysis is convenient to use if current is unknown. If ever voltage is the unknown and we are asked to use mesh analysis. It is also easy to solved by just applying Ohm's Law.
