Thevenin’s theorem says that any network can be represented by a voltage source and series resistance.
Norton’s theorem says that the same network can be represented by a current source and shunt resistance. In must be possible, therefore, to convert directly from a Thevenin form to a Norton form and vice versa. Such conversions are very useful in the world of electronics. So, here I will tell you the basic formulas which are used to make such type conversions.
Conversion in Thevenin from Norton:
RTH = RN
VTH = IN × RN
Conversion in Norton from Thevenin:
RN = RTH
IN = VTH / RTH
