Question
A device used for converting A.C.into D.C.is called–
Solution
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, solidstate diodes, silicon-controlled rectifiersandothersilicon-basedsemiconductor switches.
