Lab 1: Introduction to Analog Concepts & Measurement Tools

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.
