Sharciga Ohm ee silsiladda complete

sharciga Ohm waa mid ka mid ah caqiidada aasaasiga ah ee physics. formula guud The in ansax yahay silsiladda complete, iyo meelaha ay, ayaa sheegay in xoogga hadda waa loo siman yahay si ay qeyb ka helay qeybi qiimaha volts muujiyaan, in qiimaha oo ku muujinayaa xoogga hadda ee amperes. tiirsanaanta Tani waxay muujinaysaa in dhimista ciidamada iska caabin ah oo ka mid ah korodhka hadda. Su'aashu waxa ay imanaysaa: waxaa suurtagal ah si ay u helaan ugu dembeeyey, yaraynta iska caabin ah ay u xoq? Practice muujinaysaa in tani ay tahay wax aan macquul aheyn. sharciga Ohm ee circuit guud muujinaysaa in danab waa in la kala qaybiyey total, iska caabin ah la xoojiyey ee masaafada sida wadarta ah ee iska caabin ah ee ilaha gudaha iyo dibadda ee iska caabin ah ku tiirsan hadda. Iska yaree iska caabin gudaha nidaamka eber suurtogal ma aha. Haddii kale, siday suuragal u ah ee qaraxa batari waa mid aad u sarreeya.

Waa maxay iska caabin ah gudaha iyo dibadda, kaas oo sheegay in sharciga Ohm ee silsiladda dhameystiran? Haddii, tusaale ahaan, ku xiran circuit laambadda, in waa iska caabin dibadda in guluubka this. iska caabin ah ayaa gudaha had iyo jeer waxay ka timaadaa batteriga in ahbaa nidaamka laftiisa. Haddii batteriga waxaa loo isticmaalaa halkii unug electrochemical, sharciga Ohm ee Bannaankii oo dhan tixgelinayo iska caabin ah oo xal elektrolytka ah iyo electrodes ah. Haddii caabin dibadda ee tiro yar oo gudaha ah iyo wixii circuit xiran yahay, ka dibna waxa by-circuit gaaban socodka hadda. Qiimaha Tani waxay ugu badan ee hadda in ka duuli karaa iyada oo wareeg this. ilaha awooda ee gawaarida soo bandhigin dhaqan ee hadda -circuit gaaban, naf-gooyada ah oo muhiim ah. Sababo ammaan, waxaa ku xiran qalab dibadda, batariyo la iska caabin ah oo ku filan si looga hortago masiibada.

Iyada oo la xidhiidha taxane guud ee iska caabin ah gudaha Bannaanka waxaa loo xisaabiyaa oo ay ku resistances mid kasta oo ka mid ah ilaha hadda. In xidhiidh la midka ah ee danab oo dhan kasta qaybo otvetvlonnyh uu qiimo la mid ah sida hadda ee silsiladda unbranched waxaa la xisaabaa ayadoo ku daray doorsoomayaasha ah oo muujinaya kasta oo qaybaha ku xiran ee isku midka ah ammeters. il hadda ku taalla qayb Bannaanka saameyn ah kuma laha qayb ka barbar xiran in ay.

Meesha laga codsado sharciga Ohm ee silsiladda dhameystiran? Badanaa waxay waxaa loo isticmaalaa si loo xisaabiyo hadda ee toosan wareeggeedii korontada, DC. Si aad u qabtaan xisaabinta si sax ah, waa in la xusuusto postulates Kihgofa. Waa midda koowaade, wadarta aljabrada oo ka mid ah ciidamada hadda at Guntin waa loo siman yahay si eber. Second, wax soo saarka ee wadarta aljabrada ciidamada hadda in loop wax u xiran yihiin jahaysteen silsilad iyo jiididda qaybaha Bannaanka had iyo jeer waa loo siman yahay si ay u soo tiriya aljabrada ee danab ku ogaado in Bannaanka.

Under waxa xaaladaha, sida iyo goorta sharciga Ohm ee silsiladda dhamaystiran ayaa u furmeen? cilmi-Swiss Georg Simon Ohm in hadda caan ku wareegsan formula dunida siman u yimid. Wuxuu bartay tallaabada magnetic of hadda iyo tijaabiyay matoorrada kala duwan loo isticmaalo in ay tijaabo kirishbooyada biraha iyo Alloys kala duwan. Ohms ahaa jirka dadka ugu horeysay oo ay ku calaamadsan saamayn on caabbi ee heerkulka kaari. sharciga Ohm ee silsiladda dhamaystiran ayaa la aqoonsan beesha cilmiyeed hal mar. saynisyahan ugu horeeya ee la mahadiyo ee sharciga, ayaa noqotay cilmi Ruush Jacobi iyo Lenz. American John. Henry ka dib marka la barbar dhigo caanaha iska listo sharciga Ohm ee silsiladda complete, la jiinyeer a dhexe ee qolka a qaxay-xumida, oo ah borofisar Jarmal E. Lommel yeedhay furitaanka "Shuclada dhalaalaysa berrinkii korontada."
