Metal oxide Varistor / Zinc oxide Varistor ha e lumellane le li-resistor tse sebelisang semiconductor electrocnic ceramic element haholo-holo e entsoeng ka zinc oxide. E bitsoa varistor kapa mental oxide varistor (MOV), joalo ka ha e ela hloko phetoho ea motlakase. 'Mele oa varistor ke sebopeho sa matrix se entsoeng ka likaroloana tsa zinc oxide. Meeli ea lijo-thollo lipakeng tsa likaroloana e ts'oana le likarolo tsa motlakase tsa mateano a PN a mahlakore a mabeli. Ha motlakase o le tlase meeli ena ea lijo-thollo e maemong a phahameng a impedance mme ha voltage e le holimo ba tla ba boemong ba ho senyeha e leng mofuta oa sesebelisoa se seng se lekanang.
