I was just recently going over some old college notes and circuit problems and was wondering: In which cases is it more advantageous to use one theorem or the other? It is not as powerful as Mesh or Nodal analysis in larger networks because the use of Mesh or Nodal analysis is usually necessary in any Thevenin exercise, so it might well be used from the start.
