Norton’s theorem states that a complex network connected to a load can be replaced with an equivalent impedance Correct Answer in parallel with a current source

Concept:

  • Norton’s Theorem states that “Any linear circuit containing several energy sources and resistances can be replaced by a single constant current source in parallel with a single resistor “.
  • It is an analytical method used to change a complex circuit into a simple equivalent circuit consisting of a single resistance in parallel with a current source.

Steps to follow for Norton’s Theorem:

  • Calculate Norton’s current source by removing the load resistor from the original circuit and replacing it with a short circuit.
  • Calculating the current through a shorted wire.
  • Calculating the Norton resistance by removing all power sources in the original circuit (voltage sources shorted and current sources open).
  • Calculating total resistance between the open connection points.
  • Draw the Norton equivalent circuit, with the Norton current source in parallel with the Norton resistance.
  • The load resistor re-attaches between the two open points of the equivalent circuit.
