A module is a separate unit of software or hardware. Typical characteristics of modular components include portability, which allows them to be used in a variety of systems, and interoperability, which allows them to function with the components of other systems. The term was first used in architecture.
A silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit.It's a solid state direct current (DC) electronic switch. There is a ton of information including a detailed description of the SCR and a list of applications at the Wikipedia article.A link is posted below. silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit.
rectifier (rekÂ´tifÄ«ur) , n a device used for converting an alternating current to a direct current; it also prevents or limits the flow of current in the opposite direction. rectifier, full-wave, n an apparatus for rectifying the entire wave of an alternating current in a radiography machine by means of a mechanical rectifier or valve tube. rectifier, half-wave, n an apparatus used in the rectifying of half of the sine wave in a radiography unit.
