I SC I n I SC 54 EE1002 Introduction to Circuits and Systems 4) Thevenin resistance can then be obtained by dividing the Thevenin voltage by the Norton current. RT 5) VT IN These will be good approximations for the parameters of Thevenin and Norton equivalent circuits as the practical voltmeter and the ammeter will have a finite resistances as shown in the figure. Thevenin and Norton equivalent can be used for circuit analysis. Suppose we are asked to find the current in any branch in the circuit, we treat the concerned branch as a load and then find the Thevenin or Norton equivalent of the remaining circuit. This results in a simpler circuit, and the current in the concerned branch can be obtained easily. 55 EE1002 Introduction to Circuits and Systems Maximum power transfer Representation of circuits in their Thevenin and Norton equivalents shows that p...
