20-7 Transformers and the Transmission of Electricity
... What is a transformer good for? In general, transformers are used to change the voltage from a wall socket into a different voltage, which could be higher or lower, for use by a particular device. Some devices, such as microwave ovens and cathode ray tube televisions, require higher voltages than th ...
