Strand D: Principles and Applications of Electricity

Electricity demand changes constantly. Suppliers need to generate more electrical energy when demand is high, and less when demand is low.

The telegraph works by transmitting signals through an electrical circuit. Learn more and print your own telegraph key using this 3d model of a real artefact.

In a few decades, some of the electricity you use might be generated by bacteria.

How do magnetic fields help you get down safely from the top of a drop tower ride? Learn how electromagnetic induction works at the amusement park.

Have you ever experienced static electricity? Like when you pull a wool sweater over your head in the winter? See what else static electricity can do in this hands-on activity.
