Wht is d role of load resistance in a rectifier?

rectifier electrical device converts alternating current , periodically reverses direction, direct current , flows in 1 direction. process known rectification. physically, rectifiers take number of forms, including vacuum tube diodes, mercury-arc valves, solid-state diodes, silicon-controlled rectifiers , other silicon-based semiconductor switches. historically, synchronous electro mechanical switches , motors have been used. radio receivers, called crystal radios, used "cat's whisker" of fine wire pressing on crystal of galena serve point-contact rectifier or "crystal detector".

rectifiers have many uses, found serving components of dc power supplies , high-voltage direct current power transmission systems. rectification may serve in roles other generate direct current use source of power. noted, detectors of radio signals serve rectifiers. in gas heating systems flame rectification used detect presence of flame.

simple process of rectification produces type of dc characterized pulsating voltages , currents. depending upon type of end-use, type of dc current may further modified type of relatively constant voltage dc characteristically produced such sources batteries , solar cells.
