ET 212 Homework help

1. Construct the circuit shown in Figure 1 below in Multisim with R1 = 2.2 KΩ and R2 = 1.8 KΩ. Use a 10% tolerance for the resistors. Assume an ideal diode.

Part A:

1. Calculate current ‘I’ in the circuit shown in Figure 1. Show work.
2. Calculate the voltage drops across R1 and across R2.
3. Construct the circuit in Multisim and measure the current in the circuit using the Agilent Multimeter. Compare it to your calculated value in Step 1.
4. Using the Agilent Multimeter, measure the voltage drops across R1 and across R2, and compare it to what you calculated in Step 2.

Part B:

1. Reverse the polarity of the diode and analyze the circuit. Repeat steps 1) and 2) from Part A.
2. Construct the revised circuit in Multisim and repeat steps c) and d) from Part A.
3. Tabulate all your data below using appropriate units. Be sure to capture the screen for the measured values.

Review Questions:

1. Does the simulation results match the calculated values? If not, explain what causes this difference in the measurements.
2. What is the difference between Part A and Part B with respect to the current and voltage drop in the circuit?
