Tšimo ea Motlakase ka Lipoleiti tse Tšoanang
Tšimo ea motlakase ke khopolo ea motheo fisiks e bontšang tšebelisano-'moho lipakeng tsa lintho tse tjhajwang ka motlakase. Litšebelisong tse ngata tse sebetsang, haholo-holo boenjiniere le lisebelisoa tsa elektroniki, hangata re kopana le maemo ao tšimo ea motlakase e hlahisoang ke lipoleiti tse bapileng tse tjhajwang. Lipoleiti tsena tse bapileng li na le mefuta e mengata ea lits'ebetso, ho tloha ho li-capacitor le lisebelisoa tsa bongaka ho ea ho lisebelisoa tse fapaneng tsa elektroniki. Sehlooho sena se tla tšohla tšimo ea motlakase ka lipoleiti tse bapileng ka botebo, ho tloha khopolo-taba ea motheo ho ea lits'ebetsong tsa eona tse sebetsang.
Khopolo ea Motheo ea Tšimo ea Motlakase
Ka kakaretso, tšimo ea motlakase e hlahisoa ke tjhaja ea motlakase 'me e ka hlalosoa e le matla a fumanoang ke tjhaja e nyane e ntle ha e beoa sebakeng se itseng sebakeng. Palo ena e hlalosoa ke vector ea tšimo ea motlakase E, e nang le li-unit tsa Newtons ka Coulomb (N/C) kapa Volts ka mithara (V/m).
Ho utloisisa tšimo ea motlakase lipoleiting tse bapileng, re tla qala ka molao oa Coulomb, o bolelang hore matla a pakeng tsa litefiso tse peli tsa lintlha a lekana ka ho toba le boholo ba litefiso 'me a lekana ka tsela e fapaneng le sekwere sa sebaka se pakeng tsa tsona. Leha ho le joalo, tabeng ea lipoleiti tse bapileng, re sebetsana le kabo ea litefiso tsa holim'a metsi, eseng litefiso tsa lintlha.
Lipoleiti tse Laetsoeng tse Tšoanang
Nahana ka lipoleiti tse peli tse tsamaisang tse bapileng tse behiloeng li shebane ka sebaka se senyenyane sa d pakeng tsa tsona. Poleiti e 'ngoe e na le tjhaja e ntle ea +Q, ha poleiti e 'ngoe e na le tjhaja e mpe ea -Q. Boemo bona hangata bo sebelisoa ho theha li-capacitor, e leng likarolo tsa bohlokoa lipotolohong tse fapaneng tsa elektroniki.
Ha lipoleiti tse peli li tjhajwa, ho thehoa tšimo ea motlakase pakeng tsa tsona. Ka lebaka la kabo ea tjhaja holim'a lipoleiti (ha re nahana hore lipoleiti li kholo haholo ha li bapisoa le sebaka se pakeng tsa tsona), tšimo ea motlakase pakeng tsa lipoleiti e batla e lekana 'me e ka nkoa e sa fetohe sebakeng se itseng ho tloha moeling oa lipoleiti.
Tšimo ea Motlakase Pakeng tsa Lipoleiti tse Tšoanang
Tšimo ea motlakase pakeng tsa lipoleiti tse peli tse bapileng tse tjhajwang e ka fumanoa ho sebelisoa molao oa Gauss. Molao oa Gauss oa motlakase o bolela hore phallo eohle ea motlakase holim'a bokaholimo bo koetsoeng e lekana ka ho toba le kakaretso ea tjhaja e koetsoeng ke bokaholimo boo.
Bakeng sa lipoleiti tse bapileng, re khetha bokaholimo ba Gaussian bo silindara bo nang le mothapo o otlolohileng ho lipoleiti le lipoleiti pheletsong ka 'ngoe ea silindara. Ka lebaka la ho lekana ha bothata, tšimo ea motlakase E e otlolohile ho bokaholimo ba lipoleiti 'me e tsitsitse pakeng tsa lipoleiti.
Phallo ea motlakase holim'a silindara ea Gaussian e kenngoa feela ke lipheletso tse peli tsa silindara tse pakeng tsa lipoleiti. Ha re nahana hore sebaka sa holim'a lipoleiti ke A, re fumana:
\[ \Phi = E \cdot A – (-E \cdot A) = 2EA \]
Ho ea ka molao oa Gauss:
\[ \Phi = \frac{Q_{\text{in}}}{\varepsilon_0} \]
Moo \( Q_{\text{charge}} \) e leng tefiso yohle hodima dipoleiti mme \(\varepsilon_0\) e le tumello ya vacuum. Kaha tefiso poleiting e le nngwe ke \(+Q\),
\[ 2EA = \frac{Q}{\varepsilon_0} \]
Kahoo tšimo ea motlakase E pakeng tsa lipoleiti ke:
\[ E = \frac{Q}{2A \cdot \varepsilon_0} \]
Leha ho le jwalo, kaha ho na le poleiti e tjhajilweng hampe e tlatsetsang tshimong, tshimo yohle ya motlakase e hlahang e ba:
\[ E = \frac{Q}{A \cdot \varepsilon_0} \]
Sena se bontša hore tšimo ea motlakase pakeng tsa lipoleiti tse bapileng e tšoana 'me e itšetlehile feela ka boholo ba tjhaja, sebaka sa lipoleiti, le tumello ea sebaka se pakeng tsa lipoleiti.
