Nortons Theorem

1. Norton’s Theorem Mrs.M.Vaishnavi KIT-CBE

2. Norton’s Theorem Norton's Theorem states that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single current source and parallel resistance connected to a load .

4. Steps to Apply Norton's Theorem Step 1: Identify the load resistor Step 2: Remove the load resistor and open the terminals Step 3: Determine the short-circuit current (I_sc) Step 4: Determine the equivalent resistance (R_th) Step 5: Draw the Norton equivalent circuit Step 6: Reconnect the load resistor

5. Advantages and Limitations Norton's theorem is only applicable to linear circuits that have a constant resistance. Non-linear circuits or circuits with varying resistance cannot be simplified using Norton's theorem. Limited to DC circuits: Norton's theorem is limited to DC circuits, which means it ca
