  1. THEVENIN’S AND NORTON’S THEOREMS These are some of the most powerful analysis results to be discussed. They permit to hide information that is not relevant and concentrate in what is important to the analysis

  2. Thevenin Equivalent Circuit for PART A THEVENIN’S EQUIVALENCE THEOREM

  3. Norton Equivalent Circuit for PART A NORTON’S EQUIVALENCE THEOREM

  4. Thevenin Norton ANOTHER VIEW OF THEVENIN’S AND NORTON’S THEOREMS This equivalence can be viewed as a source transformation problem It shows how to convert a voltage source in series with a resistor into an equivalent current source in parallel with the resistor

  5. One circuit problem 1. Determine the Thevenin equivalent source Remove part B and compute the OPEN CIRCUIT voltage Second circuit problem Remove part B and compute the SHORT CIRCUIT current 2. Determine the SHORT CIRCUIT current A General Procedure to Determine the Thevenin Equivalent

  6. “Part B” LEARNING EXAMPLE USE THEVENIN TO COMPUTE Vo You have the choice on the way to partition the circuit. Make “Part A” as simple as possible Since there are only independent sources, for the Thevenin resistance we set to zero all sources and determine the equivalent resistance For the open circuit voltage we analyze the following circuit (“Part A”) ... The circuit becomes...

  7. PART B PART B LEARNING EXAMPLE: COMPUTE Vo USING NORTON COMPUTE Vo USING THEVENIN

  8. LEARNING EXAMPLE Find the Thevenin Equivalent circuit at A - B Controlling variable Thevenin equivalent Only dependent sources. Hence V_th = 0 To compute the equivalent resistance we must apply an external probe We choose to apply a current probe @V_1 @V_2 “Conventional” circuit with dependent sources - use node analysis
