Zombili izintambo ze-DC ne-AC zisetshenziselwa ukudlulisa amandla kagesi, kodwa ziyahluka ngohlobo lwamanje eziwuphethe kanye nezinhlelo zokusebenza ezithile eziklanyelwe zona.Kule mpendulo, sizohlola umehluko phakathi kwezintambo ze-DC kanye ne-AC, sihlanganisa izici ezifana nohlobo lwamanje, izici zikagesi, izinhlelo zokusebenza, nokucatshangelwa kokuphepha.
I-Direct current (DC) ingumbane kagesi ogeleza ohlangothini olulodwa kuphela.Lokhu kusho ukuthi i-voltage ne-current ihlala ingashintshi ngokuhamba kwesikhathi.I-alternating current (AC), ngakolunye uhlangothi, amandla kagesi ashintsha isiqondiso ngezikhathi ezithile, ngokuvamile ku-waveform ye-sinusoidal.I-AC yamanje ishintshana phakathi kwe-polarity enhle nengalungile, okubangela ugesi kanye namagagasi amanje ashintshe ngokuhamba kwesikhathi.
Umehluko omkhulu phakathi kwezintambo ze-DC ne-AC wuhlobo lwamanje eziklanyelwe ukuthwala.Amakhebuli e-DC aklanyelwe ngokukhethekile ukuthi aphathe intambo yamanje eqondile, kuyilapho izintambo ze-AC ziklanyelwe ngokukhethekile ukuthwala amandla ashintshanayo.Umehluko ezinhlotsheni zamanje ungaba nomthelela ekwakhiweni, ekwakhiweni nasekusebenzeni kwalezi zintambo.
Omunye umehluko omkhulu phakathi kwezintambo ze-DC kanye ne-AC yi-insulation ne-conductor materials esetshenziswa.Izintambo ze-DC ngokuvamile zidinga ukufakwa okushubile ukuze zimelane namazinga kagesi angashintshi kanye nezinguquko ze-waveform.Futhi zidinga amakhondatha amelana kancane ukuze kuncishiswe ukulahleka kwamandla.Izintambo ze-AC,
ngakolunye uhlangothi, ingasebenzisa ukwahlukanisa okuncane ngenxa yemvelo yezikhathi zokugeleza kwamanje.Bangase futhi babe nezinto ze-conductor ezihlukene zokulandisa ngomphumela wesikhumba nezinye izenzakalo eziqondene ne-AC.Izintambo ze-AC ngokuvamile zibonakala ngezilinganiso eziphezulu zamandla kagesi uma ziqhathaniswa nezintambo ze-DC.Lokhu kungenxa yokuthi ama-voltage aphezulu ezinhlelweni ze-AC angaphezulu kwesilinganiso sikagesi, futhi izintambo kufanele zikwazi ukumelana nalawa mazinga aphezulu kagesi.Ohlelweni lwe-DC, i-voltage ihlala ingashintshile, ngakho umklamo wekhebula awudingi ukwamukela amazinga aphezulu kagesi aphezulu.
Ukukhethwa kwezintambo ze-DC kanye ne-AC kuncike kakhulu kuhlelo lokusebenza.Izintambo ze-DC zivame ukusetshenziswa ezinhlelweni zamandla aphansi njengamasistimu ezimoto, amaphakethe ebhethri, namasistimu elanga.Ziyatholakala futhi ezinhlelweni zikagesi, ezokuxhumana, nezamakhompiyutha ezidinga amandla e-DC.Izintambo ze-AC, ngakolunye uhlangothi, zisetshenziswa ezinhlelweni zamandla kagesi aphezulu njengokudluliswa nokusabalalisa amandla, imishini yezimboni, izintambo zokuhlala nezokuhweba, kanye nemishini eminingi yasendlini.
Ngokuphathelene nokucatshangelwa kokuphepha, izintambo ze-AC zethula izingozi ezengeziwe uma ziqhathaniswa nezintambo ze-DC.Ngenxa yokushintshashintsha kwamandla kagesi, amakhebuli e-AC angabangela ukushaqeka kukagesi kumafrikhwensi athile noma ngaphansi kwezimo ezithile.Lokhu kusho ukuthi kufanele kuthathwe izinyathelo zokuphepha ezengeziwe lapho usebenza namakhebula e-AC, okuhlanganisa namasu afanele okubeka phansi kanye namasu okufakelwa.Ngokuphambene, izintambo ze-DC azinazo izingozi ezihlobene nemvamisa efanayo, ngakho-ke ngokuvamile zibhekwa njengeziphephile kwezinye izinhlelo zokusebenza.
Kafushane, umehluko omkhulu phakathi kwezintambo ze-DC nezintambo ze-AC wuhlobo lwamanje eziklanyelwe ukuthwala.Izintambo ze-DC zisetshenziselwa ukudlulisa amandla aqondile, kuyilapho izintambo ze-AC zisetshenziselwa ukudlulisa amandla ashintshanayo.Umehluko ohlotsheni lwamanje ungathinta ukwakheka, ukwakhiwa kanye nokusebenza kwalawa makhebula, okuhlanganisa izinto zokufakelwa kanye ne-conductor, izilinganiso zikagesi, izinhlelo zokusebenza nokucatshangelwa kokuphepha.Ukuqonda lo mehluko kubalulekile ekukhetheni ikhebula elifanele lesistimu ethile kagesi noma isicelo.
