Amandla yasendle yombane

Ukuthetha ngento amandla yentsimi yombane, kuyimfuneko ngokumbonisa ukuba kubalulekile iparameters na. Ngaphandle kwento yokuba ibinzana elithi "amandla" ngokwalo kakhulu eziqhelekileyo yaye, xa uqala kuqala, ecacileyo, kulo mzekelo, udinga nokuqonda okukuko kokuba yintoni na busengozini. Ngokomzekelo, njengoko yaziwa, amandla yentsimi yombane lingaba nokulinganiswa nakweliphi na inqanaba yayo ngendlela engaqondakaliyo, ngokuqhelekileyo elithathwa ngokuba imvelaphi (oko kukuthi, zero). Nangona oku kunika bhetyebhetye elithile kumalungiselelo izibalo, impazamo ingakukubetha amandla computing eyahlukileyo kakhulu. Okwangoku siza kucacisa kamva, usebenzisa ifomula.

Amandla yasendle yombane buhlobene ngqo impefumlelwano iintlawulo ezimbini okanye ngaphezulu ingongoma. Cinga ngemeko macala - q1 kunye q2. Amandla ezinokwenzeka intsimi yombane (kulo mzekelo - electrostatics) ichazwa njenge:

W = (1/4 * Pi * E0) / (q1 * q2 / r),

apho E0 - kwempixano, r - umgama phakathi izityholo, ngasePi - 3,141.

Ukususela endle yokuqala enza izinto yesibini (and vice versa), ngoko ezi nkalo ukuchaza nekhono. Intlawulo yokuqala onesiphumo kwi yesibini:

W = 0.5 * (q1 * Fi1 + q2 * Fi2).

Kule formula (luchazwa ngegama 1), kukho amaxabiso amabini amatsha - Fi1 kunye Fi2. We ukubala kwabo.

Fi1 = (1/4 * Pi * E0) / (q2 / r).

ngokufanelekileyo:

Fi2 = (1/4 * Pi * E0) / (q1 / r).

Ke kaloku, eyona nto yokuqala ebalulekileyo ifomula "1" iqulethe amagama amabini (q * Fi), eneneni emele amandla intsebenziswano Isigxina ngumba ka-0.5. Noko ke, amandla yentsimi yombane - asiyiyo inxalenye yayo nayiphi na intlawulo, ngoko, ukuba athathe ingqalelo kule inkalo, kufuneka nokuba sikuhambise nkusungula nokulungiswa, "0.5".

Njengoko sele kukhankanyiwe, unxibelelwano nalo ngamnye namanye amacala (akunyanzelekanga ukuba nje ezimbini). Kulo mzekelo, amandla lexinene intsimi zombane ngasentla. ixabiso layo inokufunyanwa Ebeka afunyenwe isibini ngasinye data.

Ke kaloku, emva umba ezikhethiweyo reference okhankanywe ekuqaleni kweli nqaku. Ngoko ke, ukususela fomyula, kulandela ukuba xa ubalo yenziwa ngokuphathelele amanqaku engenasizathu, umgama ukusuka izityholo okwakha Infinity, umphumo uba ixabiso umsebenzi, nto leyo eye wenza intsimi, iintlawulo ezahlukeneyo ukusuka komunye umgama ongapheliyo. Kodwa ukuba kuyimfuneko ukwazi ixabiso yomsebenzi entsimini lusenziwa intshukumo encinane ngokwentelekiso izityholo ngokwabo, indawo reference ukuze kukhethwe nokuba, ekubeni onesiphumo ixabiso ubalo izimele ezikhethiweyo reference ngongoma.

Nanku umzekelo, njengoko ungasetyenziswa izibalo pfunaka. Umzekelo, kukho ezithathu isigxina, le uqwalaselo lwesithuba yazo kanxantathu. Umgama (r) phakathi q1, q2 kunye q3 bayalingana.

Thina ukubala amandla:

Fi = 2 * (q / 4 * Pi * E0 * r).

Ngoku sikwazi lisola ngokwazo amandla intsebenziswano:

W0 = 3 * ((q * q) / 4 * 3.141 * E0 * r).

umsebenzi kuya kwenziwa xa uhambisa ukuba umgama engenamda oku.

Ukuba ukubana zontathu sisuka embindini oqhelekileyo imali elinganayo, nxantathu kwakheka enamacala R1 (ngokuchasene r ophelileyo).

Ukumisela amandla:

W = 3 * ((q * q) / 4 * Pi * E0 * R1).

Kulo mzekelo, singathetha ukunciphisa ixabiso amandla lilonke yonke inkqubo ngamacala amathathu. Kufuneka kuqatshelwe ukuba ukuba ixabiso R1 (r) ijonge Infinity, amandla lokuqala umsebenzi ovela ebantwini bewenze iyalingana.

Nzima lo msebenzi, kwaye susa ukusuka kwinkqubo a random kwentlawulo. Isiphumo ityala ezaziwa iintlawulo ezimbini zisendaweni r kude.

I-eneji kwenkqubo enjalo ilingana:

W = (q * q) / (4 * Pi * E0 * r).

Ibhokisi uya kwenza umsebenzi kwi intshukumo ngokwayo, apho ngamanani ulingana:

A = 2 * ((q * q) / 4 * Pi * E0 * r).

Ke konke nje: ngokususa esinye ntlawulo iya kukhokelela ukuba amandla iyonke ilingana zero (akukho yokususwa). Kulo mzekelo, umsebenzi kunye endle anda equalized. Ngamanye amazwi, amandla yokuqala iguqulelwa ngokupheleleyo ukusebenza.

Izibalo ezinxulumene nokuzimisela amandla intsimi yombane isetyenziswa ngokubanzi yesithuba sokukhetha capacitors. Emva isixhobo ngasinye iqulathe iipleyiti ezimbini ezahlulwe sisithuba a r umgama, kwi ngasinye apho yoyalo kanzulu.
