They showed him a one-foot-high robot that looked like a transformer.
We know that a transformer fire often leads to a power outage.
That is the "primary" of a transformer, and the "secondary" is—the iron itself, in the trough.
You know what a transformer does, but what does the name by itself convey?
He is the transformer of her, not she of him; for she will reduce man to a beast, unless he reduces her to reason.
This knob here controls a condenser, and this one a transformer.
He was not shorted by any part of the transformer or any wire he might be touching in the darkness.
The secondary of this transformer is connected to the antenn (A) and the earth (E).
A steam engine is a transformer of energy, changing caloric energy into mechanical work.
These last pieces are to form the core and part of the end of the transformer.
"device to reduce electrical currents," 1883, from French transformateur (1882); see transform.

transformer 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. ◇ 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. ◇ 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. Compare converter, rectifier. |
A device used to transfer electrical energy from one circuit to another. With an alternating current, a transformer will either raise or lower the voltage as it makes the transfer.
