What is the function of transformer? Step up or Step Down the Voltage

Question

Accepted Answer

Transformers are electrical devices used to step up or step down voltage levels in power systems.

Transformers are used to increase (step up) or decrease (step down) voltage levels in electrical power systems.
Step up transformers are used to increase voltage for long distance transmission, while step down transformers are used to decrease voltage for distribution to consumers.
Transformers work on the principle of electromagnetic induction, where changing current in one coil induces a voltage in another coil.
They are essential components in power plants, substations, and electrical distribution systems.
