Day 137: What Is A Diode?
Conceptual Physics: Here a bike light generator is connected to a voltage probe in Logger Pro. The red graph shows what we saw yesterday — the voltage cycles positive and negative (AC). The blue graph shows what happens when a diode is added to the circuit. Diodes will be important later when we use the bike generator as a battery charger.
College-Prep Physics: Based on students’ work to the M&M (light collection) lab and the properties of light activity from prior days, I decided to do a review of mathematical relationships. The handout is here: MATH RELATIONSHIPS
