Thevenin’s Theorem in electric circuits
After reading this Thevenin’s theorem topic of electric or network circuits, you will understand the theory, and also able to apply it in ac and dc circuits numerical problems.
Thevenin’s theorem states that for two terminal network NA containing linear & bidirectional elements and independent sources is equivalent to a simple network containing an independent voltage source VTh (called as Thevenin voltage) in series with the resistance RTh (called as Thevenin resistance).

Mesh Analysis in Network theory
After reading this Mesh Analysis topic of electric or network circuits, you will understand the theory and also able to apply it in numerical problems.
A mesh is a loop which does not contain any inner loop. Mesh analysis is only applicable to a planar network. A planar network is the one that can be drawn in a plane with no branches crossing one another.
