Thevenin’s Theorem is used to simplify a network to a constant voltage source with a resistance in series but Norton Theorem can be used to resolve a complex network into a constant. Current source with a resistance in parallel. Norton’s Theorem is converse of Thevenin Theorem.

source The Norton Theorem can be stated as follows.

Any two terminal networks consisting of independent voltage and current source may be replaced with an equivalent current IN is parallel with a resistance RN. Where IN is the short circuit current between the terminals of the network and RN is the equivalent resistance R­N of network as seen from the terminals but all the voltage sources short circuited and all current sources open circuit.

IN = The short circuit current supplied by the source that would flow between two terminals when they are short circuited. It is known as Norton’s Current.

RN = The equivalent resistance of the network as seen from the two terminals with all other voltage sources replaced by their internal resistances and current sources replaced by open circuit. It is known as Norton’s resistance.

Steps to solve Norton’s Theorem

To determine the current through load resistance RL, proceed with the following steps.

Remove the resistance RL in which current is to determine, thus creating an open circuit between terminals A and B.

Step-2

Calculate the short circuit current through the short load resistance RL. Thus calculated short current is known as Norton’s Current.

Redraw the network with each voltage source replaced by a short circuit in series with its internal resistance and each current source by an open circuit in parallel with its internal resistance.

Step- 5

Draw a circuit in which current IN and equivalent resistance RN connected in parallel with load resistance RL and find the current through load resistance RL.
