Difference Between Thevenin’s and Norton’s Theorem

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 RN (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
