I’ve made it to my favourite part of every physics course; circuits! When ever there are questions and problems that require you to draw out a circuit and solve it I feel like it is a fun puzzle. Week 23 in the Physics course by the Ron Paul Curriculum focused on electric circuits.
Lesson 1:
- Electric battery and basic components
- Dry cell diagram

- Connecting cells
- Electrical diagrams
- Electric current

- Types of current: DC and AC
- Sources of direct and alternating current
Lesson 2:
Practice Problems
Lesson 3:
- Resistivity: a measure of a material’s resistance to the flow of electricity


- Temperature dependance

- Work and power
- Power in circuits

Lesson 4:
- Alternating current
- Sinusoidal form

- Practice problems
