## What is Norton theorem with example?

Norton’s theorem states that any linear complex electrical circuit can be reduced into a simple electric circuit with one current and resistance connected in parallel. For understanding in depth regarding norton theory, let us consider Norton’s theorem examples as follows.

## How do you solve problems with Norton’s Theorem?

Norton’s Theorem Solved Examples for DC circuits

1. To find Norton’s current, open the load resistor and make a short circuit.
2. The next step is to find the norton’s resistance of the network.
3. To simplify the difficulty of the problem, replace the given current source into its equivalent voltage source.

What is Norton’s theorem formula?

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.

What are the application of Norton’s Theorem?

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.

### Why is Norton’s theorem not applicable for transistors?

Explanation: We can use Norton’s theorem only for linear networks. BJT is a non-linear network hence we cannot apply Norton’s theorem for it.

### 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.

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 the conclusion of Norton Theorem?

Norton’s theorem affirms that any linear electrical circuit is equivalent to an ideal current source in parallel with an equivalent resistor.

#### What is the primary practical use for Thevenin’s and Norton’s theorems?

It is very useful for analyzing power systems and other circuits where one particular load resistor in the circuit and re-calculation of the circuit is essential with each trial value of load resistance, to find the voltage across it and current through it.

#### Can Norton’s theorem be applied on a circuit containing transistor BJT?

6. Can we use Norton’s theorem on a circuit containing a BJT? Explanation: We can use Norton’s theorem only for linear networks. BJT is a non-linear network hence we cannot apply Norton’s theorem for it.

Is Norton’s theorem applicable to nonlinear circuit?

Norton’s theorem cannot be applied to non-linear circuits.

Why Norton’s theorem is dual of Thevenin’s theorem?

Explanation: Norton’s theorem is also known as the dual of Thevenin’s theorem because in Norton’s theorem we find short circuit current which is the dual of open circuit voltage-what we find in Thevenin’s theorem.
