  4. NORTON'S THEOREM Like Thevenin's theorem, Norton's theorem provides a method of reducing a more complex circuit to a simpler equivalent form. The basic difference is that Norton's theorem results in an equivalent current source in parallel with an equivalent resistance. General form of Norton's equivalent circuit. Mateen Yaqoob Department of Computer Science

  5. Norton's Equivalent Current (IN) Norton's equivalent current (IN) is the short-circuit current between two output terminals in a circuit. Norton's Equivalent Resistance (RN) The Norton equivalent resistance, RN , is the total resistance appearing between two output terminals in a given circuit with all sources replaced by their internal resistances. Mateen Yaqoob Department of Computer Science

  6. A summary of steps for theoretically applying Norton's theorem is as follows: Step-1: Short the two terminals between which you want to find the Norton equivalent circuit. Step-2: Determine the current (IN) through the shorted terminals. Step-3: Determine the resistance (RN ) between the two open terminals with all sources replaced with their internal resistances (ideal voltage sources shorted and ideal current sources opened). RN = RTH . Step-4: Connect IN and RN in parallel to produce the complete Norton equivalent for the original circuit. Mateen Yaqoob Department of Computer Science

  10. FIRST-ORDER CIRCUIT • Three passive elements (resistors, capacitors, and inductors) individually, • Circuits having various combinations of two or three of the passive elements. • RC and RL circuits. • Analysis of RC and RL circuits by applying Kirchhoff’s laws. • The differential equations resulting from analyzing RC and RL circuits are of the first order. Hence, the circuits are collectively known as first-order circuits. Mateen Yaqoob Department of Computer Science

  11. Circuit Excitation • Source-free circuits (free of independent sources) • DC Source excitation (independent sources) Mateen Yaqoob Department of Computer Science
