I-DC ne-AC inemiphumela ehlukene kumalambu. I-Direct current ingeyamanje egeleza inhlangothi eyodwa kuphela, kuyilapho i-alternating current ingeyamanje egeleza iye emuva naphambili ngendlela eyodwa.
Okwezibani, umthelela weDCfuthi i-AC ibonakala kakhulu ekukhanyeni nasekuphileni kwesibani. Ngokuvamile, amalambu angase acwayize futhi abe nempilo emfushane lapho evezwe ku-DC. Lokhu kungenxa yokuthi ngaphansi kwamandla aqondile, i-filament i-oxidize ngokushesha kunangaphansi kokushintshana kwamanje, okuholela ekuphileni kwe-bulb kufushane. Ngakolunye uhlangothi, imvamisa yamanje eshintshanayo inganciphisa ukucwayiza kwamalambu okukhanya, ngakho iphumelela kakhulu kuneyamanje eqondile.
Ngakho-ke, uma isibani siklanyelwe ukusebenza ngamandla e-AC, ukuxhuma amandla e-DC kungase kuphumele ekukhanyeni okuncishisiwe kanye nempilo efinyeziwe yesibani. Ngokufanayo, uma i-fixture yakhelwe ukusebenza ngamandla e-DC, ukuyixhuma emandleni e-AC kungase futhi kuphazamise ukusebenza kwe-bulb.
Ngaphezu kwalokho, ngaphezu komthelela wezinto zokukhanya, i-DC ne-AC inemiphumela ehlukile ekudluliselweni kwamandla nasekugcinweni.
Mayelana nokudluliswa kwamandla, ukushintshashintsha kwamandla kusebenza kahle kakhulu kumabanga amade ngoba i-voltage ingashintshwa ngama-transformer, ngaleyo ndlela kunciphise ukulahleka kwamandla.
DC amandlar inokulahlekelwa okuphezulu uma kudluliswa amandla, ngakho ifaneleka kakhulu ukudluliselwa kwamandla okuhamba ibanga elifushane, amancane. Mayelana nokugcinwa kwamandla, amandla e-DC ahambisana nokuphuma kwezinhlelo eziningi zamandla avuselelekayo (isb., amaseli elanga, izinjini zomoya) ngoba lezi zinhlelo ngokuvamile zikhiqiza amandla e-DC.
Ngakho-ke, i-DC, njengendlela yokugcina amandla, kulula ukuyisebenzisa ngokuhambisana nalezi zinhlelo zamandla avuselelekayo.
Amandla e-AC adinga ukuguqulelwa kumandla e-DC ngesiguquli ukuze ahambisane nalawa masistimu, okwengeza ubunkimbinkimbi nezindleko zokuguqulwa kwamandla.
Ngakho-ke, umthelela we-DC ne-AC ezibanini, ukudluliswa kwamandla kanye nokugcinwa kwamandla akubonakali nje kuphela ekukhanyeni nasekuphileni kwe-bulb, kodwa nasekusebenzeni kahle nasekusebenziseni amandla nokugcinwa kwamandla.
