    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Iumbhobho wamanzi ongaphantsi komhlabangumbhobho wentsimbi ojikelezayo owenziwe ngenkqubo yokuwelda i-arc engaphantsi kwamanzi enamacala amabini ngokuzenzekelayo. Umbhobho wenziwe ngee-coil zentsimbi ezisikiweyo kwaye ukhutshwa kubushushu obungaguqukiyo ukuqinisekisa ukuqina kwawo kunye nobude bawo.
