Lab 1: Introduction to Analog Concepts & Measurement Tools

Helpful Tips

The figure below demonstrates how to wire the power circuit in station 5. Note that the values themselves are not indicative of what you will actually measure. However, the layout can be followed to help you wire up the circuit correctly.

Clarifying Notes

• Circuit 5 references a Google doc where you must record your data. The link for this is on Blackboard under announcements.
• The graphs you’ll create in the lab homework require you to record current on the x-axis and voltage on the y-axis. This is weird because voltage is the IV and is plotted on the y-axis. But it is not a typo. No credit will be given to any graphs that have voltage on the x-axis and current on the y-axis. You also must include 100% of your data points in your graph, not just some of them.
