What is Nortons equivalent circuit?
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 independent source in circuit?
An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity. Similarly an independent current source maintains a current (fixed or time-varying) which is unaffected by any other quantity.
Is the Norton equivalent circuit the same as the short 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 to find Norton resistance in a circuit?
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. Draw the Norton equivalent circuit, with the Norton current source in parallel with the Norton resistance.
Which is an example of a Norton current source?
By comparing the above example with example of Thevenin’s example problem, we can observe that Norton’s equivalent circuit of a linear network constitute a Norton current source IN in parallel with a Thevenin’s resistance Rth.
How is Norton’s theorem applied to a circuit?
Theory: Norton’s theorem states that a network consists of several voltage sources, current sources and resistors with two terminals, is electrically equivalent to an ideal current source ” I NO ” and a single parallel resistor, R NO. The theorem can be applied to both A.C and D.C cases. The Norton equivalent of a circuit consists…
