Detailed explanation-1: -A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.

Detailed explanation-2: -A transformer is an electrical device that uses the principle of electromagnetic induction to transfer energy from one electric circuit to another. It is designed to either increase or decrease AC voltage between the circuits while maintaining the frequency of the current.

Detailed explanation-3: -Transformers change the voltage of the electrical signal coming out of the power plant, usually increasing (also known as “stepping up") the voltage. Transformers also reduce ("step down") the voltage in substations, and as distribution transformers.

Detailed explanation-4: -A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer.

Detailed explanation-5: -Transformers step up (increase) or step down (decrease) AC voltage using the principle of electromagnetic induction-mutual induction. A changing current in the primary coil induces an e.m.f in the secondary.
