Norton's Theorem is the dual form of Thevenin's theorem

It provides a similar technique to simplify the analysis by replacing a linear circuit with an equivalent one, known as Norton's equivalent circuit

 

Norton's Theorem - A linear two-terminal circuit can be replaced by an equivalent circuit consisting of a current source  in parallel with a resistor

The current source's value, known as the Norton current , is equal to the short-circuit current at the terminals.

The Norton resistance  is the same as the Thevenin resistance , which is the input resistance measured at the terminals when all independent sources are turned off.
