Question

1) enin equivalent. one source. The purpose of this part is to find the Thévenin cquivalent of a circuit with one source by measuring find Vo and Isc a) Construct the circuit of Figure 7. Choose R1 = R2 R, 히0kΩ and set the value ofl.-6V using the 10V b) Measure the open-circuit voltage, V and the short-circuit current, I se, and thereby find Vy,and Rm Note: Do c) Using PSpice, create a simulation of the circuit. Attach a current source (IDC on PSpice's list of sources) to the supply not attempt to measure R, directly with the ohmmeter! Explain in your report why this is a bad idea. terminals of the circuit, in a manner similar to what we did in Figure 4, and do a DC sweep of the current from at least -3 mA to 3 mA. Consult the tutorial for instructions on doing such a sweep. Plot the I-V response, as we did in Figure 2b, and include it in your laboratory report. From this plot, read off values of Voc and Is , and compare these to your theoretical calculations and the experimental measurements d) Now we'll check the values ofVI, and I by injecting a current into the circuit and measuring the voltage, as in Figure 2a. We'll use the +25V voltage source and measure the voltage it takes to inject a given amount of current into the circuit, as we did in Experiment #2. So, leaving in place the 10V supply in place for, connect the +25V supply to the terminals of the circuit read the current flowing into the circuit from the power supplys display as you adjust the voltage. Measure the voltage it takes to inject 2 ma of current into the circuit. Repeat with 0 ma. Do these points lie along the I-V curve you plotted in part lb?
