Synopsis
  • This video discusses the physics of electricity generation using animations and equations to explain the concepts.
  • Students will learn about electric generators, transformers, alternating current, and mutual inductance.
Teaching Tips

Positives

  • This video is ideal for an upper-level class.
  • The accompanying visuals make it easy to follow and understand.

Additional Prerequisites

  • Students should be familiar with geometry functions and induction.
  • This video is lesson #35 of the Crash Course Physics course.

Differentiation

  • This could be used in a physics class to explain Faraday's law.
  • A portion of this video explains the technology behind wireless charging. Students can compare and contrast how energy is transmitted through wires and wireless transmission.
  • This video could spark a discussion on the various voltages across the world and why they differ. For example, European voltage compared to United States voltage.
  • This video could be used to clarify direct current and alternating current.
Scientist Notes
In order for electricity to power our lives, it needs to be generated and then distributed. This video explains this process and how we power our homes, schools, and offices. This resource is recommended for teaching.
Standards
