The purpose of this experiment is to verify Thevenin's theorem, using the LTspice simulator. Thevenin's theorem can significantly simplify the analysis of a circuit and thus has been widely used in practice. The most important steps of obtaining the Thevenin's equivalent circuit of an analogue circuit are the determination of the Thevenin's equivalent voltage Eth and the Thevenin's equivalent resistance R Th. This experiment will use the circuit diagram shown in Fig. 2 to verify Thevenin's theorem using the LTspice simulator.

(2) Draw the Thevenin's equivalent circuit external to R5. (3) Choose a random resistance value for R5 and theoretically calculate the current through and the voltage across R5. (4) Using the chosen value of R5, build up the circuit in the LTspice simulator and measure Eth and RTh external to R5. (5) Capture the waveforms of the current through and the voltage across R5. (6) Compare the theoretical prediction with the simulation results.
