Next: What you should have
Up: Tasks
Previous: In-lab Tasks:
- The power supply you built provides volts for
your MicroStamp11. Your op-amps, however, require 9
volts. Explain how you used your power supply to power
your op-amps.
- 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?
- Please provide a list of constructive recommendations
that can be incorporated into next year's labs.
