Norton current

Find the Norton source current by removing the load resistor from the original circuit and calculating the current through a short (wire) jumping across the open connection points where the load resistor used to be.

Is Norton current short-circuit current?

Norton's Theorem: Any two terminals of a network of any number of resistors, current sources and/or voltage sources can be reduced to one current source in parallel with one resistor. The short-circuit current available from these two terminals is the Norton current.

What is Norton's theorem formula?

For the above-given circuit, Norton's Theorem formula would be: I = IN(RN/R+RN) & V= IN(RRN/R+RN).

Why Norton theorem is used?

The Norton equivalent circuit is used to represent any network of linear sources and impedances at a given frequency. Norton's theorem and its dual, Thévenin's theorem, are widely used for circuit analysis simplification and to study circuit's initial-condition and steady-state response.

What is meant by 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.

How do you use Norton's Theorem?

The basic procedure for solving a circuit using Nortons Theorem is as follows:

Remove the load resistor R_L or component concerned.
Find R_S by shorting all voltage sources or by open circuiting all the current sources.
Find I_S by placing a shorting link on the output terminals A and B.

Who made Norton's Theorem?

This chapter examines Norton's theorem, also known as Mayer's theorem, developed at the same time, in 1926, by Hans Ferdinand Mayer, researcher of Siemens & Halske in Germany, and by Edward Lawry Norton, engineer and researcher of the legendary Bell Labs in the United States.

What is the difference between Thevenin and Norton?

Thevenin's Theorem utilises a voltage source, while Norton's Theorem uses a current source. Norton's Theorem employs a resistor set in parallel over the source, whereas Thevenin's Theorem utilises a resistor in series. From Thevenin's Theorem, Norton's Theorem can be easily derived.

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 load current in Norton Theorem?

Therefore, I load = current passing through load resistance = 4A. Similarly, the large, complex, linear networks with several numbers of sources (current or voltage sources) and resistors can be reduced to simple parallel circuits with single current source in parallel with Norton's resistance and load.

Where can I find Thevenin and Norton?

Thevenin voltage is equal to Norton's current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.

What is Thevenin's Theorem formula?

Any combination of batteries and resistances with two terminals can be replaced by a single voltage source e and a single series resistor r. The value of e is the open circuit voltage at the terminals, and the value of r is e divided by the current with the terminals short circuited.

What is Max power transfer formula?

Maximum Power Transfer Formula As shown in the figure, a dc source network is connected with variable resistance RL. The fundamental Maximum Power Transfer Formula is. P m a x = V T h 2 4 R T h.

Why is Thevenin Theorem used?

Thevenin's Theorem provides an easy method for analyzing power circuits, which typically have a load that changes value during the analysis process. This theorem provides an efficient way to calculate the voltage and current flowing across a load without having to recalculate your entire circuit over again.

What is Thevenin's voltage?

As there is no current flowing through the 8 kΩ resistor, so there is no voltage drop across it and hence the voltage across the terminals AB is same as the voltage across the 4 kΩ resistor. Therefore, 12 V will appear across the AB terminals. Hence, the Thevenin's voltage, VTH = 12 V.

What is a load resistance?

Load Resistance Defined At the most basic level, load resistance is the cumulative resistance of a circuit, as seen by the voltage, current, or power source driving that circuit. This includes the resistance of the wires and the resistance of any devices connected to those wires.

What is RL in Thevenin Theorem?

Thévenin's theorem is a process by which a complex circuit is reduced to an equivalent circuit consisting of a single voltage source (VTH) in series with a single resistance (RTH) and a load resistance (RL).

Why Norton is dual of Thevenin?

Answer: The Norton's theorem establishes, dually, that any linear circuit seen from one port may be represented by a current source (with a value equal to the short-circuit current) in parallel with an impedance (with the same value as in the Thévenin's theorem). To this circuit we call the Norton configuration.

What is Thevenin and Norton circuits?

Norton's Thereom is identical to Thevenin's Theorem except that the equivalent circuit is an independent current source in parallel with an impedance (resistor). Therefore, the Norton equivalent circuit is a source transformation of the Thevenin equivalent circuit.

How do I find Thevenin voltage?

To calculate the Thevenin equivalent voltage, the load impedance is open-circuited. And find an open-circuit voltage across the load terminals. Thevenin equivalent voltage (Veq) is equal to the open-circuit voltage measured across two terminals of load.
