Ohms law, What is Tramsformer and their types, Uses

Question

Accepted Answer

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

Transformers are used to increase or decrease the voltage of an alternating current (AC) signal.
There are two main types of transformers: step-up transformers and step-down transformers.
Step-up transformers increase the voltage, while step-down transformers decrease the voltage.
Transformers are commonly used in power distribution systems to transmit electricity over long distances.
They are also used in electronic devices such as televisions, computers, and audio amplifiers to provide the appropriate voltage levels.
Examples of transformers include power transformers, distribution transformers, and autotransformers.
