2. I-AC ne-DC bathinta kanjani isikhathi eside sempahla kagesi?

Uhlobo lwe-ac-ac noma i-DC-lungathonya impilo yezemishini kagesi.Ukushintshana kwe-AC kungukushintsha kwamanje kungakhuphuka ukugqokwa ezingxenyeni ezinjenge-motors & transformers ngenxa yezinguquko zayo zokuqondisa njalo.DC, ukuhlinzeka okungamanje, kungumuntu onamadivayisi kumadivayisi owenzelwe yona, njengamalambu we-LED nemibuthano kagesi, kungenzeka ukubasiza isikhathi eside.

3. Yimiphi imithelela yemvelo yokukhiqizwa kwe-AC ne-DC?

Umthelela wezemvelo kuncike emthonjeni kagesi kunokuba kuthi noma ku-AC noma i-DC.I-DC isebenza kahle kakhulu ngezinto ezifana namandla elanga & ukugcinwa kwebhethri, ukunciphisa ukulahleka kwamandla futhi mhlawumbe kunciphise ukulimala kwemvelo.I-AC ilungele ukuhambisa ibanga elide kepha ingadinga ingqalasizinda engaphezulu engakhulisa izintambo zayo zemvelo.

4. Izinyathelo zokuphepha ziyehluka kanjani lapho zisebenza nge-AC Versus DC?

Amaphrothokholi okuphepha ayahluka phakathi kwe-AC ne-DC ngenxa yemiphumela yawo ehlukile yomzimba.I-AC ingaba yingozi ikakhulukazi ngoba ingadala izivumelwano zemisipha eziqhubekayo, okwenza kube nzima ukuyeka umthombo.I-DC imvamisa ibangela i-jolt eyodwa eqinile engacindezela umuntu kude nomthombo wamanje.Amadivaysi akhethekile okuvikela kanye nabaphula umthetho wesekethelwa aklanyelwe ukuphatha lo mehluko ngempumelelo.

5. Ngabe kukhona ubuchwepheshe obusha obusezingeni eliphezulu obungashintsha indlela esisebenzisa ngayo i-AC ne-DC?

Yebo, ubuchwepheshe obusha buyavela bungashintsha ukuthi sisebenzisa kanjani i-AC ne-DC.Ukuthuthuka kwamandla we-elekthronikhi, afana nama-inverters asebenzayo futhi angabizi kakhulu nobuchwepheshe be-solar nezobuchwepheshe bebhethri, okwenza amasistimu we-DC asebenza ngokusetshenziswa okwengeziwe.Intuthuko kubuchwepheshe obuqinile bezwe kanye nezinto zokwenziwa ze-semiconductor nazo zithuthukisa ukusebenza kahle kwe-AC-DC, okuguqula izinhlelo zokusebenza nokusebenza kwale misinyane.
