Electric Power: Putting Charges to Work

The Electric Power Video Tutorial explains the relationship between electrical power and electrical energy and uses the relationship (and others) to derive and use an equation relating power to current and electrical potential difference.

The video lesson answers the following questions:

1. What is meant by electrical power?
2. How do you calculate power?

Additional and Related Learning Tools

Minds On Physics, Electric Circuits Module, Mission EC3
A Minds On Physics mission will give you a mental workout. But when you're done, you'll feel like you know your stuff. This mission on the voltage-power-energy relationship in circuits is a good fit to the video.

Case Studies: Electric Power Concept Builder
A Concept Builder provides students an interactive questioning module with immediate feedback and question-specific help. They are always a great follow-up to a video.

Teacher Resources

Curriculum Corner, Electric Circuits Section
Our Curriculum Corner is composed of a collection of Think Sheets. Each one makes for a great component of any Lesson Plan. They work great for both independent practice exercises and cooperative group exercises. The following Think Sheet makes a great complement to this video:

Teacher Toolkits: Circuit Concepts
Try a Teacher Toolkit ... you might be very glad that you did. Each toolkit includes annotated links to vetted resources from across the web that we feel reliably support the specific topic. Give this one on circuit concepts a try.

Minds On Physics, Electric Circuits Module, Mission EC3
A Minds On Physics mission will give a student a mental workout. But when they're done, you can be confident that they have worked through the details of a concept with some degree of depth. This mission on the power-voltage-energy relationship in circuits is a good fit to the video. Use it with a Task Tracker account and have students progress tracked.

Case Studies: Electric Power Concept Builder
The first two of three activities of this Concept Builder may be suitable for viewers of this video. It is a great tool when used with a Task Tracker subscription.
