subject: Transformers And Their Utility [print this page] Almost everyone has heard about transformersAlmost everyone has heard about transformers. How they look like, what is their general use and things like that. But what most people don't know is the technicalities of a transformer. Though not very complicated but they are very interesting to know, and that is what we are here to talk about.
Technically speaking, a transformer is a device which transfers electrical energy from one circuit to another through inductively coupled conductors coils. A varying current in the first or primary winding creates a magnetic flux in the core of the device and thus a varying magnetic field through the secondary winding. This winding induces a varying electromotive force or generally speaking voltage in the secondary winding. This effect is called mutual induction. By passing and circulating such voltages, this device works, producing high quantity of energy we require.
These vary in their sizes too. From thumbnail size to the ones hidden inside a microphone to huge tonnes located at the corner of buildings. It is very difficult to find an electrical place where these cannot be found.
Basically speaking Transformers are of various types based on their usage and utility. These include: Autotransformer, Polyphase, Leakage Resonant Audio and Instrument.
