Where as Thevenin’s theorem was used to simplify a network to a constantvoltage\u00a0source and a series resistance. Norton’s theorem can be used to resolve a
\nnetwork into a constant-current source and a parallel resistance. The interchange\u00a0of voltage sources and current sources by use of Thevenin’s and Norton’s theorems
\nis sometimes useful in circuit analysis.
\nThe theorem may be stated as follows :
\nStatement : Any combination of linear bilateral circuit elements and active\u00a0sources, regardless of the connection or complexity, connected to a given load Rl can be replaced by a simple two terminal network, consisting of a single current\u00a0source of IN amperes and a single impedance RTH in parallel with it, across the
\ntwo terminals of the load RL. The In is the short circuit current flowing through\u00a0the short circuited path, replaced instead of. It is also called Norton’s current. The
\nRTH is the equivalent impedance of the given network as viewed through the load \u00a0terminals, with RL removed and all the active sources arc replaced by their internal
\nimpedances. If the internal impedances are unknown then the independent voltage\u00a0sources must be replaced by short circuit while the independent current sources
\nmust be replaced by open circuit, while calculating RTH.<\/p>\n
Steps to Apply Norton’s Theorem<\/strong><\/p>\n Step 1: Short the branch through which the current is to be calculated.<\/p>\n Step 2: The current through this short circuited branch, using any of the nets\u00a0simplification techniques. This current is Norton’s current IN.<\/p>\n Step 3: Calculate the equivalent resistance RTH, as viewed through the terminals ol\u00a0interest, by removing the branch resistance and making all the independent source; Step 4: Draw the Norton’s equivalent across the terminals of interest, showing a cuisource with the resistance RTH parallel with it<\/p>\n Step 5: Reconnect the branch resistance. Let it be RL. Then using current division\u00a0in parallel circuit of two resistances, current through the branch of interest can be Norton’s Theoram Notes Where as Thevenin’s theorem was used to simplify a network to a constantvoltage\u00a0source and a series resistance.
