Transformer how to work 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 consist of two coils, primary and secondary, wound around a magnetic core
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer
Step-up transformers increase voltage while step-down transformers decrease voltage
Isolation transformers provide electrical isolation between the input and output circuits
Autotransformers have a single winding that acts as both primary and secondary
Instrument transformers are used for measuring current and voltage in high voltage circuits
