Filogi shine na'urar da ake amfani da ita don canja wurin wutar lantarki daga tsarin kunnawa zuwa ɗakin konewar injin da kunna matsewar man fetur/iska. Filogi yana da harsashi mai zaren ƙarfe kuma an keɓe shi ta hanyar lantarki daga tsakiyar lantarki ta hanyar insulator na yumbu. Lantarki na tsakiya, wanda ƙila ya ƙunshi resistor, an haɗa shi zuwa tashar fitarwa na murɗaɗɗen wuta ko magneto ta waya mai ƙorafi. Harsashin ƙarfe na walƙiya yana zube cikin kan silinda na injin, don haka yana da ƙasa ta hanyar lantarki. Lantarki na tsakiya yana fitowa cikin ɗakin konewa ta hanyar insulator na porcelain, a ƙarshen ciki na electrode kuma yawanci, ɗaya ko fiye yana haɗuwa da ƙarshen ciki na zaren harsashi da keɓance gefen, ƙasa, ko na'urorin lantarki na ƙasa.

Matsayin filogi shine ya haifar da tartsatsi a ƙayyadadden lokaci don kunna cakuda mai konewa. An haɗa filogi zuwa babban ƙarfin lantarki da aka samar ta hanyar wutan wuta ko magneto. Lokacin da halin yanzu ke gudana daga na'urar, ana haifar da wutar lantarki tsakanin wutar lantarki ta tsakiya da na'urorin lantarki na gefe. Da farko dai babu wani motsi da zai iya gudana saboda man fetur da iskar da ke cikin wannan ratar masu insulators ne, amma yayin da wutar lantarki ta kara tashi, sai ya fara canza tsarin iskar gas tsakanin na’urorin lantarki. Da zarar ƙarfin lantarki ya wuce ƙarfin dielectric na iskar gas, gas ɗin yana ionized. Gas mai ionized ya zama jagora kuma yana ba da damar halin yanzu don gudana ta cikin rata. Tsananin zafi a cikin tashar tartsatsin yana haifar da iskar gas mai ionized ta faɗaɗa cikin sauri, kamar ƙaramin fashewa.
