types of transformers, basic principles of transformers working

Question

Accepted Answer

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

Transformers are of two types - step-up and step-down transformers
The basic principle of transformer working is electromagnetic induction
The transformer consists of two coils - primary and secondary
When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
The voltage induced in the secondary coil is proportional to the number of turns in the coil
Transformers are used in power transmission, voltage regulation, and isolation
Examples of transformers include distribution transformers, power transformers, and autotransformers
