2. Rashin fahimta game da hanyoyin da ba daidai ba a cikin lissafin amfani da makamashi
Kamfanoni da yawa sukan yi amfani da ramuwar wutar lantarki dangane da bayyananniyar ƙarfin lokacin da ake ƙididdige tasirin ceton makamashi. Misali, lokacin da motar ke gudana a cike da kaya a ƙarƙashin yanayin mitar wutar lantarki, ma'aunin aiki na yanzu shine 194A. Bayan amfani da ƙa'idar saurin mitar mai canzawa, ƙimar wutar lantarki yayin cikakken aiki yana ƙaruwa zuwa kusan 0.99. A wannan lokacin, ma'auni na yanzu shine 173A. Dalilin raguwa a halin yanzu shine cewa capacitor na tacewa na ciki na mai sauya mitar yana inganta yanayin wutar lantarki.
Dangane da lissafin wutar lantarki na fili, tasirin ceton makamashi kamar haka:

Ainihin ƙarfin wutar lantarki na mota ana ƙaddara ta motar da nauyinsa. Bayan ƙara ƙarfin wutar lantarki, nauyin motar ba ya canzawa, kuma ingancin motar ma ba ya canzawa. Saboda haka, ainihin amfani da wutar lantarki na motar ba zai canza ba. Bayan ƙara ƙarfin wutar lantarki, babu wani canji a yanayin aiki na injin, ƙarfin halin yanzu, mai aiki da igiyoyi masu amsawa. To ta yaya ake inganta yanayin wutar lantarki? Dalilin ya ta'allaka ne a cikin capacitor na tacewa a cikin mai sauya mitar, kuma wani bangare na amfani da injin shine karfin amsawa da na'urar tacewa ke samarwa.
