ProblemFind the Thevenin Solved Example by Norton’s Theorem: Example: Find RN, IN, the current flowing through and Load Voltage across the load resistor in fig (1) by using Norton’s Theorem. β =Find the Norton equivalent of the circuit at the port defined by the nodes a and b. In this Norton’s theorem also we follow the procedure similar to thevenins theorem (up to some extent) R1 = Ω. R2 = Ω. R3 = Ω. R4 = Ω. VS =V. Find Io using Thevenin’s or Norton’s theorem. We can replace the shaded part of the This problem is done in the Worked Problems: Thevenin and Norton Equivalents as Problem In this problem we have both dependent and independent sources. In the solution shown, we find the open circuit voltage and the short circuit current, and from that we calculate the Thevenin resistance Steps to determine Norton’s equivalent Resistance (R N) and Current (I N): Calculate R N in the same way as R Th. Using source transformation, the Thevenin and Norton resistances are equal i.e. E Analysis of Circuits () Thevenin and Norton–/Thévenin Theorem: Any two-terminal network consisting of resistors, fixed voltage/current Norton’s Theorem Norton theorem is used to change a complicated circuit into a simple equivalent circuit consisting of a single current source, referred to as Norton current Thevenin and Norton equivalent circuits as shown in Figure+V A B A A B Thevenin s Equivalent Norton s Equivalent FigureQ )Determine Practice ProblemΩΩ a bΩ 4v x + − + − v x Figure For Practice ProbNorton’s Theorem In, aboutyears after Thevenin published his theorem, Illinois Tech Illinois Institute of Technology THEVENIN’S THEOREMStatement: A linear two-terminal circuit can be replaced by an equivalent circuit consisting of a voltage source V Th in series with a resistor R Th, To apply Norton's Theorem to the solution of the two loop problem, consider the current through resistor Rbelow. Since the question here is to find the current through AB,Ω resistor is considered as the load. Norton’s Theorem: Step by Step Procedure with Examples. (a) To find Norton’s current, Remove the load resistor (6 Ω), short it with a wire and the circuit is redrawn as below Find Vo using Thevenin’s theorem. Problems – In class. ProblemFind the Thevenin equivalent circuit for the following circuit with respect to the terminals AB (Irwin – Example) Problems – In class. SolutionSTEPShort the Ω load resistor as shown in (Fig 2). (Recall that the "short Solved ProblemDetermine the current through AB in the given circuit using Norton’s theorem.

Problems – In class. R N = R Th. To find the Norton current I N, we determine the short-circuit current flowing from terminal a to b Illinois Tech Illinois Institute of Technology Problems – In class.
