** buy neurontin cod Norton’s Theorem**

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 I_{N} is parallel with a resistance R_{N}. Where I_{N} is the short circuit current between the terminals of the network and R_{N} is the equivalent resistance R_{N} of network as seen from the terminals but all the voltage sources short circuited and all current sources open circuit.

I_{N} = 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.

R_{N} = 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 R_{L}, proceed with the following steps.

** http://theactiveparent.com/author/theactiveparent/ Step -1**

Remove the resistance R_{L} 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 R_{L}. Thus calculated short current is known as Norton’s Current.

** cheap brand viagra no prescription Step-3**

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-4**

Determine the resistance R_{N} of the network as seen from the terminals.

**Step- 5**

Draw a circuit in which current I_{N} and equivalent resistance R_{N} connected in parallel with load resistance R_{L} and find the current through load resistance R_{L}.
