## Why is Norton dual of Thevenin?

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.

### Is Norton theorem and Thevenin theorem are same?

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 are Thevenin and Norton dual to each other?**

Thevenin and Norton’s resistances are equal. Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.

**How are Norton’s theorem and Thevenin’s theorem related?**

Thevenin’s theorem states that we can replace all the electric circuit, except a load resistor, as an independent voltage source in series, and the load resistor response will be the same. The Norton’s theorem states that we can replace the electric circuit except the load resistor as a current source in parallel.

## Why we use Norton’s theorem?

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. This is equivalent to calculating the Thevenin resistance. When there are dependent sources, the more general method must be used.

### What does Millman’s theorem yields?

It is a very useful theorem to find out the voltage across the load and current through the load. It is also called as parallel generator theorem. It is helpful to reduce a mixture of voltage and current sources connected in parallel to a single equivalent voltage or current source.

**What is Norton theorem used for?**

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 the difference between Thevenin and Norton theorem Mcq?**

What is the difference between Thevenin and Norton theorems? Norton’s theorem uses a voltage source, whereas Thevenin’s theorem uses a current source.

## How do you find ISC and VOC?

Use a voltmeter to measure the open-circuit voltage at the port of the circuit: voc = VTh. 2. Connect a short circuit across the output and use an ammeter to measure the short-circuit current: isc = IN.

### How is Norton theorem calculated?

Norton Current The value i for the current used in Norton’s Theorem is found by determining the open circuit voltage at the terminals AB and dividing it by the Norton resistance r.

**What is the dual pair of capacitance in Tellegen’s theorem?**

Explanation: The dual pair of inductance is capacitance. And the dual pair of capacitance is inductance. In an electrical circuit itself, there are pairs of terms which can be interchanged to get new circuits.

**What is Norton law?**

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.
