RI80Umuvuduko mwinshini ibikoresho bya elegitoronike bifite agaciro kihariye ko guhangana kandi bikoreshwa cyane mubuhanga bwamashanyarazi, ibikoresho bya elegitoronike nubushakashatsi bwubushakashatsi. Igikorwa cyacyo nyamukuru ni ukugabanya inzira yimigezi igezweho kugirango umuzenguruko ukore mumurongo wateganijwe wa voltage, bityo ukingire umutekano wibindi bikoresho nibikoresho.
Mbere ya byose, imbaraga zo hejuru za voltage nigikoresho kirwanya gifite agaciro karenze RI80. Kurwanya ni isano iri hagati yigitonyanga cya voltage yakozwe mugihe ikinyuze muri yo, kandi igice cyayo ni ohms (Ω). Kurwanya imbaraga za voltage nyinshi birwanya ubusanzwe birenze 100Megaohms (MΩ), ishobora kwihanganira voltage nyinshi kandi ikagira uruhare mukugabanya imiyoboro yumuzingiUmurimo wingenzi wa R80amashanyarazi menshini ukugabanya ibiyobora murwego rwo gushushanya no gukumira umuyaga ukabije kwangiza ibindi bikoresho nibikoresho. Mubikorwa bifatika, niba igishushanyo mbonera cyumuzunguruko ari amp 1, ibindi bice bigize umuzunguruko bigomba kuba bishobora kwihanganira amp 1 yumuriro niba nta mbogamizi nini ya voltage irwanya. Nyamara, ibice bimwe (nka capacator, imiyoboro ihuriweho, nibindi) ntibishobora kwihanganira imigezi miremire, kubwibyo bigomba gukenera kugarukira mukoresheje amashanyarazi menshi. Byongeye kandi, amashanyarazi arwanya imbaraga arashobora kandi guhagarika imikorere yumuzunguruko, kugabanya ingaruka zurusaku rwamashanyarazi kubindi bice, kandi bigatanga voltage nukuri hamwe nubu.
I80amashanyarazi menshizikoreshwa cyane muri sisitemu yimbaraga. Kurugero, mumashanyarazi no gukwirakwiza imiyoboro, amashanyarazi arwanya imbaraga arashobora gukoreshwa kugirango agabanye ibihe byinshi kandi arinde impinduka ninsinga z'amashanyarazi.
Iyo umuzunguruko mugufi cyangwa amakosa bibaye mugihe cyo kohereza amashanyarazi, résistor-ristoriste irashobora kugabanya ingano yumuriro wamashanyarazi hanyuma igahagarika umuyaga mugihe kugirango impanuka itaguka. Byongeye kandi, amashanyarazi arwanya imbaraga nayo agira uruhare runini mugushakisha ingufu.
