What is a Norton equivalent circuit?
The Norton equivalent circuit represents a general circuit with an independent current source in parallel with the Norton equivalent Resistance. Norton current source ( ) is equivalent to the short-circuit current at the terminal a and b. Norton resistance is th e same as the Thévenin resistance.

How will you express the Norton’s equivalent circuit from Thevenin’s equivalent circuit?
Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.
What is Norton equivalent resistance?
Nortons theorem 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. Norton on the other hand reduces his circuit down to a single resistance in parallel with a constant current source.
What is Norton’s theorem and why is it relevant to your work?
Norton Theorem says that any circuitry which has many power supplies and resistors can be swapped with the circuit which has current source and one resistor in its parallel. This theorem is appropriate to both AC and DC circuitries. It works in AC circuits for impedance and resistance calculations.
What is Norton’s equivalent resistance?
Any collection of batteries and resistances with two terminals is electrically equivalent to an ideal current source i in parallel with a single resistor r. The value of r is the same as that in the Thevenin equivalent and the current i can be found by dividing the open circuit voltage by r.
How is Norton theorem applied?
Applications of Norton’s Theorem It is used to reduce a complex circuit into a simple circuit. Norton’s theorem is useful to solve problems on parallel generators with unequal emf’s and unequal impedances. Norton’s theorem can be interchangeably used with thevenin’s theorem through proper source transformations.
What is Norton’s Theorem?
What is Norton’s Theorem? Norton’s Theorem states that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single current source and parallel resistance connected to a load.
What is Norton theorem formula?
Norton equivalent circuit consists of an equivalent impedance connected parallel with a current source and load resistance. The constant current source used in Norton equivalent circuit is known as Norton current I N or short circuit current I SC. Norton theorem was derived by Hans Ferdinand Mayer and Edward Lawry Norton in 1926.
How to calculate Norton equivalent resistance?
To calculate the Norton equivalent resistance for a circuit having a dependent source, we need to calculate the open-circuit voltage (V OC) across the load terminals. Open-circuit voltage is similar to the Thevenin equivalent voltage.
How do you find the equivalent resistance of a circuit?
To determine internal resistance or Norton equivalent resistance R N of the network under consideration, remove the branch between A and B and also replace the voltage source by its internal resistance. Now the equivalent resistance as viewed from open terminals A and B is R N,
