What's transformer working and types?

Question

Accepted Answer

Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.

Transformers work on the principle of electromagnetic induction
They are used to increase or decrease voltage levels in electrical circuits
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer
Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels
Isolation transformers are used to isolate a circuit from the power source
Autotransformers have a single winding that acts as both the primary and secondary winding
Instrument transformers are used to measure voltage and current levels in electrical circuits
