Metal oxide Varistor / Zinc oxide Varistor haina-mutsetse resistor inoshandisa semiconductor electrocnic zvedongo chinhu chinonyanya kuumbwa ne zinc oxide. Inodaidzwa kuti varistor kana mental oxide varistor (MOV), sezvazvinoenderana nekuchinja kwemagetsi. Muviri wevaristor chimiro chematriki chinoumbwa neinc oxide particles. Iyo miganhu yezviyo pakati pezvimedu yakafanana neyakafanana magetsi emagetsi enzira mbiri dzePN. Kana iyo voltage iri pasi iyi miganhu yezviyo iri mune yakanyanya impedance nyika uye kana iyo voltage yakakwira ivo vanozove vari mune yekuparara mamiriro inova iri mhando yeasina-mitsara mudziyo.
