Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

Transformers are used to either step up or step down voltage levels.
Step down transformers decrease voltage levels, while step up transformers increase voltage levels.
Types of transformers include power transformers, distribution transformers, isolation transformers, autotransformers, and instrument transformers.
Power transformers are used in power generation and transmission, while distribution transformers are used in the distribution of power to end-users.
Isolation transformers are used to isolate a circuit from the power source, while autotransformers are used to step up or step down voltage levels in a single coil.
Instrument transformers are used to measure voltage and current levels in power systems.
