Detailed explanation-1: -Transformers use electromagnetic induction to change the voltage and current. This change is called transformer action, and describes how the transformer changes an AC signal from its primary to its secondary component (like in the equation above).

Detailed explanation-2: -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.

Detailed explanation-3: -A transformer is a device which can change the of the induced alternating voltage.

Detailed explanation-4: -Complete answer: A transformer cannot convert AC to DC or DC to AC. The transformer has the ability to step up or decrease current. A step-up transformer is a transformer that raises the voltage from the primary to the secondary.

Detailed explanation-5: -A transformer is an inductive electrical device for changing the voltage of alternating current. A transformer consists of two magnetically coupled coils. Alternating current in one (called the “primary") creates a changing magnetic field which induces a current in the second coil (the “secondary").
