Umthetho Ohm kaThixo ngenxa chain epheleleyo

umthetho Ohm kaThixo yenye iinkolelo ezisisiseko physics. Le ndlela yokubala ngokubanzi ukuthi sisebenza nangenxa yezinto epheleleyo, kwaye endaweni yayo, wathi ngobunzulu yangoku lilingana QUOTIENT afunyenwe ngokwahlula ixabiso volts ebonisa, ukuba ixabiso evakalisa inqaba yangoku amperes. Oku kuxhomekeka ibonisa ukuba ukunciphisa amandla kweelana ukunyuka yangoku. Umbuzo ngulo: ngaba unako ukufumana kakhulu ngoku, ukunciphisa kwinkcaso ekuqaleni? Practice ibonisa ukuba oku akunakwenzeka. umthetho Ohm ngenxa sekethe iyonke ibonisa ukuba ombane kufuneka lahlulwe ngetotali, uxhathiso idibene kumgama njengoko lodibaniso kweelana zangaphandle nezangaphakathi yemvelaphi yangoku ukuxhathisa-oxhomekeke. Ukunciphisa uxhathiso yangaphakathi kwenkqubo kunothi akwenzeki. Kungenjalo, amathuba dubulo battery uphezulu kakhulu.

Yintoni luvukelo ngaphakathi nangaphandle, leyo umthetho Ohm ithi ukuba chain epheleleyo? Ukuba, umzekelo, liqhagamshelene wesekethe isibane, oko kukuthi ukuxhathisa zangaphandle kweli ibhalbhu. Luvukelo yangaphakathi isoloko lisuka kwebhetri eyenziwe ngaphakathi kwinkqubo ngokwayo. Ukuba ibhetri iyasetyenziswa endaweni yeseli electrochemical, umthetho Ohm ngayo yonke le sekethe ithatha ingqalelo uxhathiso yesisombululo electrolyte kwaye i electrode. Ukuba uxhathiso lwangaphandle iqhezu embilwini emasikwini le sekethe ivaliwe, ngoko yiyo uhamba mfutshane-wesekethe. Eli xabiso liphezulu yangoku ezinokuthi kuqukuqela ngale wesekethe. imithombo Amandla iimoto kubonisa amaxabiso olukhoyo elifutshane wesekethe, ubomi emngciphekweni ezibalulekileyo. Ngenxa yezizathu zokhuseleko, elidityaniswe kuyo izixhobo zangaphandle, iibhetri nayo ngokwaneleyo ukuthintela le ntlekele.

Xa uxhulumaniso series luvukelo iyonke yangaphakathi kumphathi wesekethe ibalwa ngokudibanisa resistances ngamnye kule mithombo yangoku. Xa uxhulumaniso engumzekelo i ombane kuzo iinxalenye nganye otvetvlonnyh unalo ixabiso efanayo njengoko zangoku kwi kwikhonkco unbranched ibalwa ngokudibanisa izinto ezibonisa ammeters ngalinye amacandelo enxulumene ngaxeshanye. umthombo ngoku isendaweni isabelo wesekethe alunasiphumo kwi kwinxalenye parallel elidityaniswe kuyo.

Apho isicelo umthetho Ohm ukwenzela chain epheleleyo? Isikakhulu ke asetyenziswa ukubala ngoku kumgama owazisayo iisekethe zombane, DC. Ukwenza izibalo kakuhle, kufuneka ikhunjulwe postulates Kihgofa. Okokuqala, isixa aljibra zemikhosi zangoku kwi esiludumbo ilingana zero. Okwesibini, imveliso isixa aljibra yomkhosi ngoku nayiphi loop evaliweyo branched chain notsalo amacandelo wesekethe usoloko lilingane sum aljibra le ombane ibonakele kwisekethe.

Kuphantsi kwaziphi iimeko, njani yaye nini umthetho Ohm ukwenzela chain epheleleyo iye yavulwa? ngumphandi Swiss Georg Simon Ohm weza ngoku waduma ehlabathini ifomula jikelele empirically. Wafunda intshukumo kazibuthe ngoku lisebenzisa umbane eyahlukeneyo esetyenziswa ukuhlola zabo abaqhubi zesinyithi ezahlukeneyo kunye aluminium. Ohms waba yamachiza yokuqala yaphawula ukusebenza kwinkcaso lobushushu umqhubi. umthetho Ohm ukwenzela chain epheleleyo kuye kwaqatshelwa yi kuluntu lwezenzululwazi kwangoko. Sisazinzulu sokuqala ukuba siqonde umthetho, baye babe ngabaphandi Russian Jacobi kunye Lenz. kamva American uYohane. uHenry wafanisa esichaza umthetho Ohm ukwenzela chain epheleleyo, kunye uziphu embindini kwigumbi ongemhle ibhungane, kunye unjingalwazi yaseJamani E. Lommel ebizwa ukuvulwa "itotshi eliqaqambileyo entsimini kombane."
