Transformer
From Wikipedia, the free encyclopedia
A transformer is a device that moves electrical energy from one circuit to another through electromagnetism. They are an important part of electrical systems.[1]
Transformers can come in many different sizes, from a very small coupling transformer inside a stage microphone to big units that weigh hundreds of tons used in power grids.
The main reason to use a transformer is to make power of one voltage into power of another voltage. More voltage is easier to send a long distance, but less voltage is easier to use in the home.[2]
