Transformer works on the Faraday’s Law of Electromagnetic Induction. It is a process by which primary coil induces a voltage into secondary coil with the help of magnetic induction. The coil windings are electrically isolated and magnetically connected around a common circuit called core.
Transformer in physics is described as a device that is used in the power transmission of electric energy. Learn more about the working principle, types along with diagrams.
Things I remember about transformers:
The main purpose of a transformer is to change voltage from one level to another--you can change to a lower or higher voltage as desired.
Power supplied to a transformer must be alternating current--applying DC current gives you noise, smoke and fire...
Transformers for three-phase power must have three distinct windings....
