How can you find the 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.
How do you solve a Norton circuit?
The basic procedure for solving a circuit using Nortons Theorem is as follows:
- Remove the load resistor RL or component concerned.
- Find RS by shorting all voltage sources or by open circuiting all the current sources.
- Find IS by placing a shorting link on the output terminals A and B.
How do I calculate Norton’s resistance?
(2) Find the Norton resistance by removing all power sources in the original circuit (voltage sources shorted and current sources open) and calculating total resistance between the open connection points.
What is the Norton current?
Explanation: Norton current is obtained by shorting the specified terminals. So, it is the short circuit current. It is not the open circuit current because if specified terminals get open circuited then current is equal to zero.
What is the formula of Norton theorem?
In this example, the Norton current is obtained from the open circuit voltage (the Thevenin voltage) divided by the resistance r. This resistance is the same as the Thevenin resistance, the resistance looking back from AB with V1 replaced by a short circuit. since R1 and R3 form a simple voltage divider. = Ω.
What is another name of Norton current in Norton theorem?
Norton’s equivalent circuit
It states that any two terminal linear network or circuit can be represented with an equivalent network or circuit, which consists of a current source in parallel with a resistor. It is known as Norton’s equivalent circuit.
How do you find Norton’s current in a short circuit?
To find Norton’s current, open the load resistor and make a short circuit. Then find the current through the short-circuited terminal by any network analysis method. This short circuit current is called as Norton’s current. Here we have three currents I 1, I 2, and I 3.
How to calculate Norton’s theorem for DC circuits?
Now redraw the circuit with Norton’s current source in parallel with the norton’s resistance. Then add the load resistor in parallel with the above circuit to form norton’s equivalent circuit for the given circuit. Apply current division rule at node A, and find the load current.
What are the impedances of Norton’s equivalent circuit?
The Norton’s equivalent circuit has a single current source called Norton’s current source (I N), equivalent impedance called Norton’s equivalent impedance Z N and a load impedance Z L. In the above equivalent circuit, Norton’s current IN is nothing but a short-circuit current, which is obtained by shorting the load impedance Z L.
How to convert Norton to Thevenin equivalent circuit?
As we have seen, the Norton equivalent circuit consists of a Norton current source and Thevenin equivalent circuit consists of a Thevenin voltage source. The equivalent resistance is the same in both cases. To convert Norton to Thevenin equivalent circuit, source transformation is used.
