Semiconductors and Diode Theory

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) for the circuit. Show work.
  2. Calculate the voltage drops across R1 and across R2.
  3. Measure total current for the circuit and compare it to your calculated value in step 1. Be sure to provide a screenshot displaying the measured result.
  4. Measure the voltage drops across R1 and across R2, and compare it to what you calculated in step 2. Include a screenshot.

Part (B)

Reverse the polarity of the diode and construct the circuit.  Repeat steps 3 and 4 above.

  1. Tabulate all your data, both calculated and measured, using units and headings as appropriate.
  2. Explain differences, if any, between your calculated and measured results in Part A. In detail and in words, explain the differences in results for Part B in relation to Part A.
