Le matla a mogote ea morao-rao ea motlakase le kopo lona e sebetsang

The le lebaka la ho futhumatsang mokhanni itšetlehile ka 'nete ea hore matla a ea dieleketerone ho fallela ho eona (ka mantsoe a mang, matla a hona joale) ka thulana latellanang tsa likaroloana le ions ea limolek'hule lekhoakhoa la tšepe elements e fetoloa mofuta mofuthu ea matla kapa Q, e le thehoa ke poleloana e reng "mogote input".

mosebetsi oa hona joale e lekanya ho sebelisa tsamaiso ea machaba ea diyuniti, ka ho sebelisa tlhokeng joules (J), matla a ho utloisisa hona joale o ikemiselitse e le "Watt" (W). A tloha ho tsamaiso ea ka liketso, ka 'na ea sebelisoa ho akarelletsa batho bao e seng SI diyuniti hore lekanya mosebetsi hona joale. Har'a bona WH (W × h) e kilowatt-hora (khutsufalitsoe KW × h). Ka mohlala, 1 × W H bolela mosebetsi hona joale le matla a itseng a ho 1 Watt le bolelele ba nako ea hora e 'ngoe.

Ha dieleketerone susumelletsa hammoho mokhanni ema tsa tšepe, tabeng ena kaofela e metle mosebetsing generated jwale e aba bakeng futhumatsang mohaho tšepe, 'me, e thehiloeng dipehelo tsa molao tsa paballo ea matla, e ka hlalosoang ke moralo wa Q = A = IUt = Ke ² RT = (U ² / R) * sa t. likamano tse kang tseo le sebetsa ka ho nepahetseng bontša molao tsebahalang ea Joule. Histori, ho ne ho ea pele ke ikemiselitse empirically rasaense D. Joel ka bohareng ba lekholo la bo19 la lilemo, 'me ka nako e tšoanang, le nosi, ke rasaense e mong - E.Lentsem. E sebetsang kopo ya matla mogote fumanoa ka tshebetso botekgeniki ea qaptjoa ho ka 1873 ke Russia moenjiniere A. Ladygin ba tloaelehileng litleloubu mabone.

Thermal matla khumo e sebetsa a 'maloa a lisebelisoa tsa motlakase le ditlhomo liindasteri, e leng ka ho mogote ditlabelwa, futhumatsang, tse kang liontong motlakase, inventory motlakase tjheseletsa thepa e le lintho tse tloaelehileng haholo disebediswa ba ntlo ea ka e le hantle motlakase futhumatsang - litanka, kulo litšepeng, kettles, litšepeng.

O fumana ka boeona 'me phello mogote ho indasteri e lijo. Le karolo e khōlō ea sebelisoa motlakase-futhumatsang monyetla hore etsa bonnete ba bokgoni mogote. Ke hobane hona joale le matla a mogote amang sehlahisoa lijo, e leng e na le lengolo la e itseng ea ho hanyetsa, a etsa hore e heats evenly. E mong a ka bolela e le mohlala oa kamoo ho disoseji hlahiswa: ka e le nama monei khethehileng minced kena ka hlobo tšepe, mabota a lona a boela a sebeletse e le li-electrode. Ho na le e fana ka ea kamehla junifomo futhumatsang fetela sebakeng lohle le bophahamo ba modumo ea sehlahiswa, mocheso batlang e hlokomelwa homolog boleng tsa likokoana-hloko tsa sehlahisoa lijo, hammoho le lintlha tsena nako ya tshebetso theknoloji le tshebediso ya matla ke tlaase-tlaase.

The itseng mocheso bokgoni ba motlakase hona joale (ω), ka mantsoe a mang - ka tjhelete e ea mocheso hore o lokolloa ka unit trust bophahamo ba modumo ka itseng unit trust nako e balwa ka tsela e latelang. Elemental cylindrical mokhanni bophahamo ba modumo (DV), le e-karolo leketla sefapanong lithapo DS, bolelele legal dl, e tšoanang le ho tataiso ea morao-rao, 'me ho hanyetsa ke abel R = leq (legal dl / DS) , DV = dSdl.

Ho ea ka litlhaloso molao Joule, bakeng sa nako e abetsoeng (bang dt) ka ho ikopanya le bophahamo ba modumo nkiloe ba bile teng ba mocheso boemo ba lekanang dQ = Ke ² Rdt = leq (legal dl / DS) (jdS) ² bang dt = pj ² dVdt. Tabeng ena, ω = (dQ) / (dVdt ) = pj ^2, 'me bonang! Ho sebelisa molao Ohm ya ho theha jwale segokanyipalo ya j = γE karo-karolelano le leq = 1 / γ, hang-hang re fumana polelo e reng ω = Je = γE ^2. Ho ka differential sebopeho fana khopolo ea molao Joule e.
