A lab report for a university course on circuit theory ii (elec195). The report details an experiment where thevenin's theorem is used to calculate the load voltage and load current for a given series-parallel circuit. A schematic, required equations, and a procedure for constructing the circuit and measuring the necessary parameters. The results are then verified using pspice simulation.

To calculate the load voltage and load current using Thevenin’s Theorem. To verify your results by using Pspice simulation to verify the load voltage and load current for the circuit.

DISCUSSION: The series-parallel circuit shown in Figure #1 is to be analyzed using Thevenin’s Theorem. During this experiment you will measure Thevenin’s equivalent circuit and subsequently verify your results using Pspice. Thevenin’s equivalent voltage directly measured as the open-circuit voltage with the load capacitor, CL removed. Thevenin’s equivalent impedance will be calculated by first measuring the following parameters; vOC (open-circuit voltage) and iSC (short-circuit current) and then satisfying the equation given below: ZTH = vOC / iSC
