Smaller transformers are used to reduce voltage from the wall socket to a household electrical device such as a computer.
Transient adaptation
The expansion and contraction of the eye as it moves from areas of different illumination, for example a dim vdt to a bright spotlight. Excessive transient adaptation usually results in eye fatigue.

Transmission
The process of sending or moving electricity from one point to another; usually defines that part of an electric utility's electric power lines from the power plant buss to the last transformer before the customer's connection.
Transmission and distribution losses
The losses that result from inherent resistance in electrical conductors and transformation inefficiencies in distribution transformers in a transmission and distribution network.
Transmission lines
Transmit high-voltage electricity from the transformer to the electric distribution system.
