**Difference Between Thevenin’s and Norton’s Theorem**

- Norton’s theorem is converse of
Thevenin’s theorem in the respect that Norton equivalent circuit uses a current
generator instead of voltage generator and the resistance
**R****N**(which is the same as**RTh**) in parallel with the generator instead of being in series with it.- Thevenin’s theorem is a voltage form of an equivalent circuit where as Norton’s theorem is a current form of an equivalent circuit.

- The mathematical relation between the two circuit is
**RN = RTh ; IN = VTh/ RTh**
