Kuyini voltage ezifundeni kagesi,

Sonke siyazi ukuthi ukuze uvule izibani, cindezela rotary inkinobho inkinobho, chofoza kukho. Chofoza - futhi izibani isibani up, ukhanyisa nxazonke. Ngokuvamile, bambalwa abantu abacabanga izinqubo ezenzeka kulezi zikhathi. Eqinisweni, abacwaningi abaningi babe iminyaka abazinikele ukuthola ukuthi iyini voltage zamanje.

Ngu Isifaniso nge uketshezi gama lisho "zamanje" kuzwakele kubo bonke - esivusa iqondiswe, ukugeleza. Mayelana nogesi, kuba ukunyakaza ngendlela ehlelekile. izinhlayiya iyimbi futhi nakanjani icala. Kubalulekile ukukhumbula ukuthi akusiwona nje mayelana electron, kodwa yayihlanganisa nokuthi la ma-athomu, ukulahlekelwa kwabo. Icala electron alivumi, kodwa ion (ama-athomu okukhulunywa) - omuhle. Qonda lokho kuyinto voltage, isibonelo esilandelayo sizokusiza.

Ake sicabange isu elilula: kwesibani incandescent, inkinobho exhunywe kwi-ukudabuka ka Omunye walabo ababili efingqa izintambo, futhi ugesi. Isibani zikhanyiswe, kumelwe kuqala kunazo zonke ukuqonda ukuthi ikuphi umehluko voltage phakathi ezinyakazayo yemvelo izinhlayiya futhi zibe namandla.

I wire sensimbi zenziwe ngama-athomu, okuyinto njalo kuvela ukunyakaza engokwemvelo electron. Nokho, i-zamanje kulesi simo akuyona njengoba kukhona disordered (senhlekelele, okungezona ohlangothini) ukunyakaza kwabo. Izinhlayiyana "amabutho" sigudluke endleleni efanele yasendle kagesi. umthombo wayo zingakhiqiza ugesi e iziteshi amandla, izakhi zamakhemikhali, njll phakathi amandla amanje nawesikhathi ensimini, okubangela it, kukhona ubuhlobo ngqo :. Njengoba kwanda ubukhulu emkhakheni kagesi inyuka zamanje.

Ngokuvamile, wamanje - inombolo izinhlayiya aphansi "lidlule" ngokusebenzisa umqhubi per unit isikhathi. Icala Imininingwane kwadingeka ukuba kudlule isikhathi electron ulinganiswa coulombs. Ngakho, iyunithi wamanje, uhlelo ampere, iyona ophethe 1 coulomb edabula umqhubi elingu-1.

Nokho, ngaphandle ukuqonda ukuthi zinamandla ezinjalo, akunakwenzeka ukucacisa inombolo sokuncika zamanje enkundleni kagesi. Empeleni, insimu ungamandla elenza electron ngamunye (noma elengayo) ukuhambisa endaweni efanele. Nokho, kusukela ngo-ukubaluleka emkhakheni kuhlukile iphuzu umqhubi ngamunye, kwanqunywa elichaza ukusebenza ngaphandle kwenkokhiso ukufuduka, hhayi amandla abstract.

Ngakho, lo voltage - umehluko ezingaba yonkana imikhawulo okuphambene umqhubi exhunywe kwi-umthombo EMF. Voltage ulinganiswa volts. Ngenxa yale njongo idivayisi ekhethekile - a voltmeter. Ixhumeke yonkana umthwalo: isibonelo eshiwo ngenhla iphenya ezimbili voltmeter exhunywe kwi-abafanele ezimbili oxhumana kwesibani. Lokhu kuvumela ukukala umfutho ensimini phakathi kwalezi amaphuzu.

Ngenxa ukucaciseleka, ungacabanga ngokwayo "ukuziphatha" izinhlayiya icala umqhubi. Electronic, njengoba sekushiwo, has a icala ezimbi, ngakho-ke, ukhangwa zesandulela okuphambene icala uphawu. Ayanda lokuhlushwa ion ngasiphi pole, ama-electron, ngaphezulu khulula e umqhubi (ngoba - ezinye athomu). Lokhu umehluko phakathi isilinganiso "-" futhi "+" is nginomdlandla.

Field (voltage) eyenziwe ngo izitshalo amandla. Kususelwa umthetho lokungeniswa kagesi e emigqeni umqhubi intersecting le kazibuthe, amandla electromotive. Just ukuxhuma umthwalo bese udala circuit, njengoba kuzovela voltage. I wamandla wangaphandle ugesi (amanzi, umusi, umoya) ushayela electromagnet, okuholela emkhakheni yayo kule Windings EMF. emazombezombe ngamunye amafomu isigaba. Iningi kabanzi okhombisa voltage. Ukudala ku oscillator abakhona ngqo ezintathu Windings ahlelwe ngendlela ethile (okusalele emuva komunye nomunye ngu degrees 120).
