Norton Theorem
- Explain Norton’s Theorem.
- Outline the procedure adopted when using Norton’s Theorem.
- Determine the short circuit current ISC and the equivalent Resistance RN (parallel)
- Construct circuit base on Norton’s Theorem.
- Solve linear circuits problem using Norton’s Theorem.
It is possible to reduce a complex circuit to a single current source and parallel resistance connected to a load.
Steps:- Remove the load resistor RL or component concerned and short circuit the terminals. Find IN on the output terminals A and B.
- Short-circuit the two voltage sources and open circuit terminals A and B, the two resistors are now connected together in parallel. Find RN.
- Having found both the short circuit current, IN and equivalent internal resistance, RN. Draw the Nortons equivalent.
- Replace the original load resistor (remove resistor) connected across terminals A and B and calculate current, I.
