Detailed explanation-1: -a) Transformer: Transformers are capable of either increasing or decreasing the voltage and current levels of their supply, without modifying its frequency, or the quantity of wattage being transferred from one winding to a different via the magnetic circuit.

Detailed explanation-2: -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.

Detailed explanation-3: -A transformer is a device that increases or decreases the voltage and current of two linked AC circuits.

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: -A transformer is a device that either increases or decreases the voltage of alternating current. Step-up transformer increases the voltage of alternating current whereas step-down transformer decreases the voltage of alternating current.
