Prelab - Read Lab 3 before beginning the calculations for the prelab. Bold items must be turned in as part of your written prelab. 1. Refer to the circuit in Figure 3.3. Solve for the voltage across the 1k2 resistor using superposition. Make sure to solve for the following 3 cases: Only V1 present, only V2 present, and both VI and V2 present. Fill out the column corresponding to Part D in Table 3.1. Show all steps to receive full credit. V₁ = 4V ww ΙΚΩ 5.1kn www 2kn 5.1kΩ 2kn V₂ = 3V Figure 3.3 2. Simulate the circuit in Figure 3.3 in SPICE. Print your schematic with all voltages and currents displayed to hand in to your TA. You can test the superposition principle by running 2 more simulations: one with V₁ replaced with a short and one with V₂ replaced with a short. You do not need to print all of the schematics to turn in. However, you should run the simulations and fill out the entries in Table 3.1. Keep a copy of your results to use when you prepare your lab report. Lab 3: Equivalent Networks and Superposition 3. Simulate the circuit in Figure 3.4. You will want to use part 1N4148 for the diode in SPICE. Print the schematic with voltages and currents displayed to hand in to your TA. Again, test the superposition principle by running 2 more simulations: first with V₁ replaced with a short and second with V₂ replaced with a short. You do not need to print all of the schematics to turn in. Finish filling out Table 3.1. Page 3
