HV yumbura ƙarfafawa China : A ka'ida (a zaton cewa capacitor tsarkakakke ne), mafi girman karfin aiki, karami ne da kuma mafi girman mita ta hanyar. Amma a zahiri, masu karfin wuta sama da 1μF yawancinsu sune masu karfin wutan lantarki, yanada matukar karfin shigar da abu, don haka idan yazama mai yawa, to matsalar zata karu sabanin haka. Wani lokaci mukan ga mafi girman karfin wutar lantarki a layi daya da karamin capacitor, babba ya wuce low-frequency yayin da karami zai wuce mitar. Tasirin capacitor shine wucewa mai saurin-mita da tsayayyen mitar. Mafi girman ƙarfin ƙarfin, sauƙin ƙananan mita zai iya wucewa. Kullum ana amfani dashi a tace,HV kofa na ƙwaƙwalwa (1000μF) tace mitar mitar, kuma low capacitance (20pF) tace mai saurin mita. Masu amfani suna da hoton abin sarrafa matatar a matsayin "tafki." Kamar yadda ƙarfin lantarki a cikin kwandon ba zai canza kwatsam ba, sabili da haka, mafi girman mita, mafi girman haɓakawa. Capacarfin yana aiki kamar tafki kuma ƙarfinsa kamar ruwa ne, tafki bazai canza ba ta ƙara fewan ruwa ko ƙarancin ruwa. Yana fassara canjin lantarki zuwa canji na yanzu, mafi girman mita, mafi girman ƙwanƙolin halin yanzu, wanda ke yin ƙarfin ƙarfin lantarki. Tace hanya ce kawai ta caji da sallama.
