A DC ne daban-daban daga AC da kuma yadda za a maida?

Constant lantarki - shi ne yunkuri na barbashi tare da cajin a wani shugabanci. Wannan shi ne, ta irin ƙarfin lantarki ko ƙarfin (characterizing dabi'u) da wannan darajar da shugabanci. Wannan abin da DC ne daban-daban daga AC. Amma dubi duk abin da a oda.

A tarihin fitowan da kuma "yaki na igiyoyin"

DC halin yanzu ake kira galvanic saboda da cewa shi aka bude a sakamakon galvanic dauki. Thomas Edison kokarin wuce shi tare da Lines na lantarki watsa. Duk da yake muhawara da aka gudanar tsakanin masana kimiyya a kan wannan batun. Su ma samu da sunan "yaki na igiyoyin". Shi ne mai tambaya na zabar matsayin core, AC ko DC. "Yin yãƙi" da aka lashe ta sãɓãwar launukansa ra'ayoyi a matsayin na dindindin bears gagarumin hasarori, ana canjawa wuri daga nesa nesa. Amma ga fasalin da m view akwai wani ƙunci, wancan ne abin DC ne daban-daban daga AC. Saboda haka, karshen sauƙi canja wurin ko a tsawon nisa.

A DC ne daban-daban daga AC da kuma abin da yake ta hanyar daga tushen ga mabukaci?

Saboda haka, a m kira na yanzu da za a iya bambanta a shugabanci da kuma girma ga wasu lokaci. Sigogi da suke a lokaci guda biya da hankali ga ne da mita da kuma irin ƙarfin lantarki. A Rasha alternating halin yanzu ciyar da zuwa lantarki iyali networks da ciwon wani irin ƙarfin lantarki na 220 V da kuma mita 50 Hz. AC mita - da yawan canje-canje zuwa takamaiman lura da barbashi a cikin wani biyu shugabanci. Sai dai itace cewa a 50 Hz, ya canjãwa shugabanci da hamsin sau abin DC ne daban-daban daga AC.

Its tushen ne soket cewa ya haɗu gida kayan karkashin daban-daban irin ƙarfin lantarki.
