Kimwe na capacator, insinga z'amashanyarazi, nyuma yo kubika amafaranga no kubyara amashanyarazi, zirashobora kurekura umuriro no gukomeza umurima w'amashanyarazi mugihe runaka. Muri iki gikorwa cyo kubika no kurekura amafaranga, insinga z'amashanyarazi zifite ihindagurika ryimbaraga zumuriro wamashanyarazi nubucucike bwumuriro, ibintu bikunze kugira ingaruka kumiterere ya kabili no mumikorere.
Intsinga z'amashanyarazi zirashobora kugereranwa na capacator haba muburyo ndetse no mubikorwa. Mu buryo bwubaka, umuyobozi, insulator, hamwe nicyuma cyo hanze mumugozi birasa cyane na electrode, dielectric, hamwe nibikoresho bitwikiriye hanze muri capacitor. Imikorere - ubwenge, ibipimo bya kabili, nkimbaraga zikora, imbaraga zidasanzwe, hamwe nubwuzuzanye, birasa cyane nubushobozi bwa capacator.
