Norton's Theorem

Norton´s equivalent circuit is the dual of Thevenin´s equivalent circuit, and may be obtained from the latter by source transformation Problem that given above. Explicitly, Norton´s theorem may be stated as follows: At the terminals 12 in Fig. (a), the arbitrary linear network A, containing resistances and energy sources, can be replaced by an equivalent circuit consisting of a current source i N in parallel with  a conductance GN, shown in Fig. (b). Problem: The current IN is the short-circuit current (through 12, when these terminals are short-circuited) and GN is the ratio of the short-circuit current to the open-circuit voltage. it is to be noted that GN = 1/ RTh where RTh is the Thevenin equivalent resistance.
