Khadadka beerta Electric. sal-dhigida

Kala scalar oo beerta dulinka (haddii ay taasi ku noqon doonaa dulinka garoonka koronto). Iyadoo la raacayo, ay qaabeeyey hawlaha scalar ama dulinka ah wadataa iyo waqti.

beerta Scalar qeexayaa shaqo ee foomka φ ah. beeraha noocan oo kale ah lagu soo bandhigay muuqaal karaa iyadoo la isticmaalayo isla heerka dusha: φ (x, y, z) = c, c = const.

Waxaanu ku qeexnaa dulinka ah, kaas oo si toos ah xagga koritaanka φ shaqo ugu badnaan.

Qiimaha waadaxa ah ee dulinka this go'aamiso heerka isbedelka ee φ shaqo ah.

Sida iska cad, oo duurka ku scalar abuuraa beerta dulinka ah.

arimahan korontada waxaa lagu magacaabaa iman kara, iyo φ function waxaa lagu magacaabaa awood. isla heerka dusha loo yaqaan meelaha equipotential. Tusaale ahaan, ka fiirsan beerta koronto.

Wixii beeraha soo bandhigay muuqaalka dhiso wax-u khadadka korontada beerta. Laakiinse waxaa la yidhaahdaa, khadadka dulinka. Taabte line Tani waxay u barta taasoo muujinaysa jihada duurka korontada. Tirada khadadka oo dhex maraya aagga unug saami qiimaha waadaxa ah ee dulinka ah.

Waxaan soo bandhigo fikradda guud ee kala duwan dulinka weheliyaan l line a a. dulinka Tan waxaa si toos ah ay weheliyaan Taabte si l line iyo qiimaha buuxda waa loo siman yahay si dl kala duwan ee.

Ka soo qaad siiyay beer qaarkood koronto, kaas oo loo baahan yahay in la qiyaaso sida khadadka duurka jooga. In si kale loo dhigo, aan go'aan ka Wehliyaha ee ballaarinta (xanuunka foosha) dulinka k inay ku beeganto kala duwan ee. Sinay qaybaha kala duwan iyo dulinka ah, waxaan ka heli nidaamka isleegyo. Ka dib is-dhexgalka, aad dhiso karo isla'eg ah khadadka korontada.

hawlgalka falanqaynta dulinka ah in ay bixiyaan macluumaadka ku saabsan khadadka xoog duurka korontada dhacaan kiis gaar ah. Waxaan soo bandhigo fikirka ah "dulinka ka daadanayo" dushiisa S. Qeexidda rasmiga ah ee socodka F waa sida soo socota: qiimaha waxaa loo arkaa wax soo saarka ee DS faraqa caadiga ah in ay unit dulinka caadiga ah si ay s dusha sare. Orth la doorto si ay u qeexayaa korka ah bannaanka caadiga ah.

eegtahay dhexeeya fikradda beerta socodka iyo socodka xaalka: walax halkii unit of time maraa dusha sare taas oo markeeda dadab iyo in ay beerta socodka. Haddii khadadka xoog duurka electrostatic ku yaalaan dusha ka dusha S, ka dibna socodka waa ay wanaagsan tahay, oo haddii aan iska eafiya iskana - xun. Guud ahaan, webigu ku qiyaasi karaan tirada of khadadka Beertayda ah lagana rujiyey. Dhinaca kale, ka daadanayo saami ay tirada khadadka xoog gelin element dusha sare.

kala ee function dulinka ah waxaa loo xisaabiyaa at hal dhibic oo la nidar ΔV mugga. S - dusha daboolaya ΔV mugga. dhibic kala Operation in meel bannaan oo u ogolaanaya in sifaha joogitaanka dhexdeeda ilo beerta. Inta lagu guda jiro riixo dusha S at P barta khadadka korontada beerta cabaar dusha sare, sii joogo tiro la mid ah. Haddii aan boos jirin ilo dhibic duurka (baxsiga ama godka), ka dibna dusha compressive a markan xaddiga fiilooyinka korantada, laga bilaabo xilligan gaar ah loo siman yahay si eber (tirada khadadka gudahood dusha S waa loo siman yahay in tirada khadadka ka imaanaya dusha this).

The L muhiim loop xiran go'aaminta hawlgalka rotor waxaa lagu magacaabaa wareegga ah ee korontada ay weheliyaan dusha ee rotor ah L. Operation tilmaamay dhibic field in meel bannaan oo. jihada rotor ay go'aamiso magnitude oo duurka u xiran socodka agagaarka dhibic siiyey (field rotor tilmaamay Uubo) iyo jihada. Iyada oo ku saleysan go'aan ka soo baxay rotor ah, by transformations sahlan loo xisaabin karaa dulinka qiyaas korontada ee Cartesian ah habka dhidibada, iyo khadadka korontada beerta.
