This unit serves looks at the concepts from Unit 8 and apply them in creating and analyzing electric circuits. These topics will account for ~6-8% of the AP exam questions and will take approximately 9-12 45 minute class periods to cover.
Applicable Big Ideas
- Big Idea #1: Systems - Objects and systems have properties such as mass and charge. Systems may have an internal structure.
- Big Idea #5: Conservation - Changes that occur as a result of interactions are constrained by conservation laws.
