Physics Course Online: Physics (Part 3): Electricity

"My daughter enjoyed Dr. Scott's easy approach to this complex topic." -- Sue B.

Course Overview

Physics Part 3: Electricity is an advanced physics continuation course.

Take this course after completing both Intro to Physics (Part 1) and Physics Part 2: Waves.

The course is about electricity. What is it, how it’s made, and how humans use it in circuits. We’ll consider everyday electrical devices like lights, the electrical grid, and computers.

  3. Recognize how household electrical devices work
  4. Understand electrical energy

Course Topics

Lesson 1: Microphones

We learn how microphones convert pressure waves (sound) into electricity.

Lesson 2: Voltage

We learn about voltage, which is a form of electrical potential energy.

Lesson 3: Current

We learn about current, and how electrical current is generated. We learn about AC and DC electricity.

Lesson 4: Power

We learn about power and the unit Watts (W).

Lesson 5: Circuits

We analyze simple circuits, including loads in parallel and series.

Course Sequence

Meet Your Instructor

Hi, I’m Dr. Scott, the course instructor and author of the digital materials that you get with the course.

As a former college professor, engineer, and scientist, I think it’s really strange that most learners don’t get much physics until about their last year of high school, if at all. Physics is all around us. And it really doesn’t take tons of annoying math to appreciate it.

The focus of my courses is a practical physics education, and we’ll strategically avoid most of the complicated equations, weird math, and long calculations that plague the typical physics classroom.
