Any network having two terminals A and B can be replaced by a current source of output Ia in parallel with a resistance Ra.
i) The output Ia of the current source is equal to the current that would flow through AB when A and B are short circuited.
ii) The resistance Ra is the resistance of the network measured between terminals A and B with load (Rc) removed and sources of e.m.f replaced by their internal resistances, if any
Norton's theorem is converse of thevenin's theorem.
