Pepala lotsekera magetsi ndi chinthu chapadera chotchingira chomwe chimagwiritsidwa ntchito popereka chitetezo chamagetsi pazida zamagetsi ndi mabwalo.
Pepala lotsekera magetsiali ndi katundu wabwino wotchinjiriza magetsi ndipo amatha kuletsa bwino kuyenda kwapano, potero amalepheretsa mabwalo amfupi pakati pa zida zamagetsi mudera kapena pakati pa mabwalo. Imatha kupirira voteji inayake ndikuletsa kutayikira ndi kutaya mphamvu yamagetsi, motero kuonetsetsa kuti dera likuyenda bwino.
Imakhalanso ndi kukhazikika kwabwino kwa kutentha ndipo imatha kupirira kusintha kwina kwa kutentha ndi kupsinjika kwa kutentha. Izi zimathandiza kuti zisunge mphamvu zake zotetezera magetsi zikagwiritsidwa ntchito kumalo otentha kwambiri popanda kusungunuka kapena kupunduka.
Ambiri, ntchito ya
pepala losungunula magetsindi kupereka chitetezo chotetezedwa chamagetsi chamagetsi pazida zamagetsi ndi mabwalo, kupewa kutayikira kwapano, kuzungulira kwachidule ndi kusokoneza, ndipo nthawi yomweyo kupereka kudzipatula kwadzidzidzi komanso kugwira ntchito kwa capacitance kuonetsetsa kuti dera likuyenda bwino.
