This is a quantitative approach to Ohm's Law involving a comparison of different resistors, as well as an observation of the non-ohmic response of a lightbulb. It is intended as a follow-up to a more qualitative introduction to series and parallel circuit building, but does not depend explicitly on previous knowledge of circuits.
Student Objectives
- Correctly construct DC circuits based on schematic diagrams
- Demonstrate Ohm’s Law quantitatively
- Learn to use the color-band system to identify standard resistors
- Distinguish between ohmic and non-ohmic behavior using a graphical representation
