The definition of a transformer is a person or thing that changes, or a device with two or more coils of wire that transfer alternating current energy from one coil to another at the same frequency but with changed voltage.

An example of a transformer is a fictional creature that changes from a person into a dog.

A static device that couples two circuits for the purpose of transferring alternating current (AC) from one circuit to another by electromagnetic induction. The current remains at the same frequency, but may change in voltage, phase, or impedance values.A transformer comprises two or more wire coils, or windings, but no moving parts.The voltage induced in a coil on a transformer is proportional to the number of turns around the core. See also AC, frequency, impedance, inductance, phase, and voltage.

(electrical engineering) A static device that transfers electric energy from one circuit to another by magnetic coupling. Their main use is to transfer energy between different voltage levels, which allows choosing most appropriate voltage for power generation, transmission and distribution separately.

A device used to change the voltage of an alternating current in one circuit to a different voltage in a second circuit, or to partially isolate two circuits from each other. Transformers consist of two or more coils of conducting material, such as wire, wrapped around a core (often made of iron). The magnetic field produced by an alternating current in one coil induces a similar current in the other coils. &diamf3; If there are fewer turns on the coil that carries the source of the power than there are on a second coil, the second coil will provide the same power but at a higher voltage. This is called a step-up transformer. &diamf3; If there are fewer turns on the second coil than on the source coil, the outgoing power will have a lower voltage. This is called a step-down transformer.
