AC Transformer

Curated and Reviewed by Lesson Planet

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control the voltage as well as the number of windings on both the primary and secondary side of the transformer.
