Thevinin and Norton

  1. Jun 13, 2010 #1
    What is the basic difference between a thevinin equivalent and a norton equivalent ? !

    Can we assume that Ith (from the thevinin) and In (from the Norton) are same ? !

    The basic difference is, for the given complex circuit with many elements, in Thevenin terms, we find equivalent voltage Vth and resistance Rth across a point AB ie., the circuit is simplified in to a voltage source in series with a resistance connected to AB.
    While in Norton terms, we find equivalent current source and parallel resistance across AB. They are just two ways of representing the same thing.
    Also note [itex] Ith \neq In [/itex]

    We always joked in school that Norton stole Thevenin's therem by doing a source transformation. :)
