Okombane ngoku. Kulula

Umbuzo wukuphi amandla ombane wamanzi akuyona into elula. Ukuba yinto echanekileyo, kunzima kakhulu. Kodwa le ngenye yeengcamango ezisisiseko zombini we-physics kunye nezinye izikhokelo zenzululwazi ezinxulumene nombane. Ubomi bemihla ngemihla, nathi sihlala sisisebenzisa le ngcamango.

Ngaphandle kokungena kwiinkcazo ezicacileyo zento ekhoyo yombane kunye nokuba yeyiphi imvelo yayo, siya kusebenzisa ukufana nomlambo ukuqonda iinkqubo ezihambelana nayo. Amanzi aphuma kummandla ophezulu olele phantsi. Okwenziwe ngombane wamandla, le meko iyafana ngokufanayo, iphuma kummandla kunye neendawo eziphezulu ukuya kwindawo ephantsi. Ubungakanani bokubahluko olwabiwo lubizwa ngokuba yi-voltage, echazwe yileta U kwaye ilinganiswa kwiiyunithi ezibizwa ngokuba yi-volts.

Masibuyele kumlambo. Xa amanzi ephuma ukusuka ekuphakameni ukuya e-lowland, inani elithile lamanzi lihanjiswa ukusuka kwenye indawo ukuya kwelinye. Xa ukuhamba kwamanje, kwenzeka into efanayo: umbane othile udluliselwa ukusuka kwenye indawo ukuya kwenye. Ukulinganisa le nkqubo, kukho ixesha elikhoyo lamandla , lichazwe njengomlinganiselo wombane oye wadlula ngexesha leyunithi ngecandelo lomqhubi. Ngokufana nomlambo, oku kuthetha ukuba amanzi amaninzi adlulisele njani kwisiza esikhethiweyo kwiyunithi yexesha. Ubungakanani obukhoyo bubonakaliswe ngophawu, ngenxa yokulinganisa kwayo kukho iyunithi ekhethekileyo-ampere.

Ezi ngcamango zombini - umbane wombane kunye nokukhoyo - usebenza njengempawu eziphambili zombane wamandla.

Amanzi, aphuma ukusuka phezulu, athatha amandla athile. Ukuba, ngokomzekelo, ukuwa kwiindawo zokuqhuma i-turbine, kuya kubangela ukujikeleza kwe-turbine kwaye wenze umsebenzi othile. Ngokufanayo, umbane wamandla ungasebenza. Lo msebenzi, okwenziwa kwesibini, ngowamandla okhoyo wamandla kagesi. Iyakwamkelwa ukuba yonyulwe nguleta P, kwaye ilinganiswa kumatts.

Umsebenzi owenziwe ngamanzi ekwindla unqunywe ngumlinganiselo wayo owela kwiintambo ze-turbine, kunye nokuphakama kwawo. Amanzi amaninzi kunye nokuphakama kokuphakama kwaloo nto iyawa, umsebenzi omkhulu ukwenziwa. Ngokufanayo, omkhulu umbane (umda wokuphakama kwamanzi) kunye nokukhoyo (okt, inani lamanzi), umsebenzi omkhulu owenziweyo kwaye, ngoko ke, amandla okhoyo kagesi.

Ukuba sizama ukwenza lo mbono, ke yonke into ingabonakaliswa ngomhlathi olula:

P = I * U,

Kuphi: I-P - kagesi ngoku, kwi-watts;

Mna-amandla okwangoku, ngokukhupha;

U yi-voltage, kwi-volts.

Le yindlela esemiselweyo yokumisela amandla wamandla kagesi.

Nangona kunjalo, umbane wamanzi awuqhubi kwenye indawo kwiimeko ezingabonakaliyo, kodwa kwii-circuits zangempela, ezineempawu zazo. Ngokukodwa, umqhubi unokumelana, kwaye umbane U kunye nekhoyo ngoku ndidibaniselana komnye wesiphaluka apho ukuqhutyelwa kwamanzi okuqhubekayo kudlulela ukuxhatshazwa kwe-Ohm. Ngoko, amandla kwisiphaluka seDC angabonakaliswa , ukuba kunyanzelekile, ngoxhatshazo, okanye uqwalasele iimpawu zesiphaluka kwimbonakalo yamandla ngoku ngoku kunye nombane odibene nomthetho ka-Ohm.

Ngenxa yokuba isiphaluka inokuxhathisa, akuwona wonke amandla asetyenziswayo ukwenza umsebenzi onobuchule. Icandelo lalo lilahlekile xa lidlula ngethungelwano. Ngoko ke, amandla angenayo, Amandla omthombo wamandla kufuneka abe mkhulu kunegunya elifunekayo ukwenza umsebenzi othile. I-so-balance balance energy kufuneka yenziwe - amandla anikwe ngumthombo kufuneka alingana namandla omthwalo ogqityiweyo kunye namandla alahlekileyo kumqhubi wamandla kagesi.

Phantse ngoko unako ukufumana ingcamango ngokubanzi yintoni na amandla ombane wamandla, ukuba uzimisele kangakanani, apho kuxhomekeke kuyo.
