I-voltage ingenye yalezi zici zokuphila zansuku zonke ezivame ukuzinakwa. Sifaka kalula ukuvula izibani noma cindezela izinkinobho ukuze kusebenze izixhobo, konke ngaphandle kokukunikeza umcabango omkhulu wesibili. Ugesi ukhona yonke indawo, futhi kuye kwaba njalo ngaleyo ndlela iningi lethu. Kodwa uma uzinika isikhashana ucabanga, ungase uzibuze ngalokhu okuyisisekelo ukuthi amandla wonke umhlaba. Kungase kubonakale kungabonakali okuncane, kodwa umthamo wezinto olula ukuwuqonda kalula njengebhakede lamanzi.
Incazelo kanye nokusetshenziswa
I-voltage ichazwa njengamandla e-electromotive noma amandla angamandla kagesi ahlukene phakathi kwamaphoyinti amabili (ngokuvamile esingaphansi komongo wesigesi kagesi) ngayinye yenkokhelo, evezwe nge-volts (V). I-voltage, kanye neyamanje nokuphikisa, isetshenziselwa ukuchaza ukuziphatha kwama-electron. Ubuhlobo bubonakala ngokusebenzisa umthetho we- Ohms nemithetho yesifunda kaKirchhoff .
Ukubizwa ngegama: vohl • tij
Isibonelo: Igridi kagesi yase-United States isebenza ku-120 V (ku-60 Hz), okusho ukuthi umuntu angasebenzisa isamukeli se-stereo engu-120 nge-pair of izikhulumi. Kodwa ukuze isamukeli esifanayo se-stereo sisebenze ngokuphepha e-Australia, esisebenza ku-240 V (ku-50 Hz), omunye angadinga amandla okuguqula amandla (futhi i-adapter ye-plug) ngoba konke kuhluka ngesizwe.
Ingxoxo
Imibono ye-voltage, icala, yamanje, nokumelana ingachazwa ngebhakede lamanzi nebhodi elihlanganiswe phansi. Amanzi amelela ukushaja (nokuhamba kwama-electron). Ukugeleza kwamanzi nge-hose kubonisa okwamanje. Ububanzi be-hose bumele ukumelana; i-hose yesikhumba ingaba nokugeleza okuncane kune-hose enkulu. Inani lomshini owenziwe ekupheleni kwe-hose ngamanzi limelela amandla.
Uma ngabe uzothululela i-gallon yamanzi ebhakede ngenkathi uhlanganisa ukuphela kwephasi ngesithupha sakho, ingcindezi ozizwayo ngesithupha isifana nokuthi i-voltage isebenza kanjani. Ukungafani kwamandla phakathi kwamaphuzu amabili - phezulu komugqa wamanzi nokuphela kwe-hose - kungumlenze wamanzi nje. Manje ake sithi usuthole ibhakede elikhulu ngokwanele lokugcwaliswa ngamagremu angu-450 amanzi (cishe ngokwanele ukugcwalisa ibhubhu elishisayo lomuntu ongu-6). Ake ucabange uhlobo lokucindezela isithupha sakho esingase uzizwe ngenkathi uzama ukubamba lawo manzi amaningi. Ngokuqinisekile okuningi 'push'.
I-voltage (imbangela) yikho okwenza okwamanje (umphumela) kwenzeke; ngaphandle komshini wokucindezela ukuyiphoqa, bekungeke kube khona ukugeleza kwama-electron. Inani lokugeleza kwe-electron elidalwa yi-voltage kubalulekile ngokuqondene nomsebenzi okudingeka wenziwe. Amabhethri ambalwa ka-1.5 V AA akudingayo ukuze usebenzise ithoyizi elincane elilawulwa kude. Kodwa awungeke ulindele ukuthi amabhethri afanayo akwazi ukusebenzisa uhlelo lokusebenza oludingekayo oludinga i-120 V, njengesiqandisisi noma esomile izingubo. Kubalulekile ukucabangela ukucaciswa kwamandla kagesi, ikakhulukazi uma kuqhathaniswa nezilinganiso zokuvikelwa kwabakhusekeli abahamba phambili .
