Next: What you should have Up: Tasks Previous: In-lab Tasks:

Post-Lab Tasks:

  1. The power supply you built provides $5$ volts for your MicroStamp11. Your op-amps, however, require 9 volts. Explain how you used your power supply to power your op-amps.
  2. Compare the voltage-load characteristics you plotted in the Pre-Lab and In-lab tasks. Explain any differences between your Pre-Lab and In-lab results. Finally use the data you gathered in your In-lab task to determine a Thevenin equivalent circuit for the power supplies that use the voltage regulator and compare this against the Thevenin equivalent circuit for the zener-diode based power supply. This should include plots of the data. Which power supply is the better?
  3. Please provide a list of constructive recommendations that can be incorporated into next year's labs.
