Transformer vs. Alternator — What's the Difference?

A device used to transfer electric energy from one circuit to another, especially a pair of multiply wound, inductively coupled wire coils that effect such a transfer with a change in voltage, current, phase, or other electric characteristic.

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.

A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core.

An electric generator that produces alternating current.

One that transforms:a transformer of recruits into soldiers.

(electrical engineering) An electric generator which produces alternating current through mechanical means.

Something that transforms, changing its own or another thing's shape.

An electric generator or dynamo for producing alternating currents.

(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.

An old term for an electric generator that produces alternating current (especially in automobiles)

(machine learning) A neural network architecture that relies on self-attention mechanisms.

Alternative case form of Transformer

One who, or that which, transforms. Specif. (Elec.), an apparatus for producing from a given electrical current another current of different voltage.

A toy consisting of a figure or representation of an object, constructed of interlocking parts in such a way that a series of turning or twisting motions of the parts can transform the object from one type of object to a different type of object, such as from an animal to an automobile.

An electrical device by which alternating current of one voltage is changed to another voltage
