What is Transformers

Transformers:

Transformers do not actually make conversion between mechanical and electrical form, but they transfer electric power from one circuit to another circuit. They can decrease or increase the voltage while transferring the power without changing the frequency, but with the corresponding increase or decrease in the current. Transformers also belong to electrical machines.
Step up transformers increases the voltage level from primary to secondary but with the corresponding decrease in
the current and vice versa.
