n: a device for changing alternating current to direct current or vice versa;usually, if the device changes AC to DC, it is called a rectifier.

n: (OSHA) the first business with employees within the customs territory of the United States that receives hazardous chemicals produced in other countries for the purpose of supplying them to distributors or employers within the United States. impressed-current anode n: anode to which an external source of IK>sitive electricity is applied (such as from a rectifier or DC generator). The negative electricity is applied to a pipeline. casing. or other structure to be protected by the impressedcurrent method of cathodic protection.

n: a device used to convert alternating current into direct current.

n: a permanent magnet meter with a rectifier built in to convert AC to DC.

abbr: silicon-controlled rectifier.

n: an arrangement of siliconcontrolled rectifiers into a common electrical bridge circuit.

n: a solid (such as gennanium or silicon) whose electrical conductivity lies between that of a conductor and that of an insulator. Semiconductor materials are used in the manufacture of diode rectifiers, transistors, and integrated circuits.

n: a device that changes alternating current to direct current by means of a silicon control gate. Commonly called SCR or Thyristor.

n: see silicon-controlled rectifier.
