TRANSFORMER

Transformer

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force or voltage in the secondary winding. Transformers can be used to vary the relative voltage of circuits or isolate them, or both.

transformer

Noun

  1. Something that transforms, changing its own or another thing's shape.
  2. 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.
