1. Given the circuit in Figure 2, determine the resistance R₂ such that V₁ = VB. Then find the voltages Vд and VB. Show steps of your calculations. 20 V R₁ 500 Ω. 0 R3 200 Ω R4 R₂ 50 Ω Figure 2: Circuit for Exercise 1 2. Use Multisim Schematics to create the circuit in Figure 3. Assign the resistor R₂ value based on your calculations in previous step. Run the simulation to obtain the DC voltage at terminals VA and VB. Compare the values with the calculated voltages in previous step. Are they identical? Take a screenshot of your Multisim circuit schematic, showing the voltage values, and include it to your lab report. Vs -20V XMM1 +. R1 500 Σ R3 2000 XMM2 R2 R4 ≥500 Figure 3: Multisim Simulation Circuit with instruments for Exercise 1 3. Add a 100 resistor between terminals VA and VB and connect an ammeter to measure the current through the resistor. Is the current value consistent with the expected theoretical value? Justify your answer. Take a screenshot of your Multisim circuit…
