transformer | | |
n. (artifact) | 1. transformer | an electrical device by which alternating current of one voltage is changed to another voltage. |
| ~ coil | a transformer that supplies high voltage to spark plugs in a gasoline engine. |
| ~ electrical device | a device that produces or is powered by electricity. |
| ~ induction coil | a coil for producing a high voltage from a low-voltage source. |
| ~ primary coil, primary winding, primary | coil forming the part of an electrical circuit such that changing current in it induces a current in a neighboring circuit.; "current through the primary coil induces current in the secondary coil" |
| ~ secondary coil, secondary winding, secondary | coil such that current is induced in it by passing a current through the primary coil. |
| ~ step-down transformer | a transformer that reduces voltage. |
| ~ step-up transformer | a transformer that increases voltage. |
| ~ tesla coil | a step-up transformer with an air core; used to produce high voltages at high frequencies. |
| ~ voltage regulator | a transformer whose voltage ratio of transformation can be adjusted. |
