Capacitance ntawm ob-xaim kab

Yog hais tias ob lub conductors a thiab b raug them rov qab, thiab qhov sib txawv ntawm lawv yog xoom, ces lub peev xwm ntawm txhua tus neeg xyuas pib yog muab los ntawm 1/2 V.ab. Capacitance C yog hu ua capacitance mus nruab nrab los yog capacitance rau hauv av.

Kuj nug, vim li cas thiaj muaj peev xwm nyob hauv kab kis tau tus mob?

Capacitance hauv a kis kab mob tshwm sim vim muaj peev xwm sib txawv ntawm cov conductors. Cov conductors tau them tib yam li cov paib sib npaug ntawm a capacitor . Capacitance nruab nrab ntawm ob parallel conductors nyob ntawm qhov loj thiab qhov sib txawv ntawm cov conductors.

Ib yam li ntawd, shunt capacitance yog dab tsi hauv cov kab sib kis? Tshem tawm capacitance hauv kis kab mob ua rau voltage amplification (Feranti nyhuv). Qhov tau txais qhov kawg voltage yuav dhau los ua ob npaug ntawm qhov xa tawm qhov kawg (feem ntau yog tias ntev heev cov kab sib kis ). Kom them nyiaj, shunt inductors yog txuas nrog thoob plaws lub kis kab mob.

Tsis tas li cov lus nug yog, vim li cas peb thiaj nrhiav tau kab rau nruab nrab capacitance hauv 3 theem system?

Cov kab rau nruab nrab capacitance nyob rau hauv ib tug nruab nrab voltage qhov system ntsuas kom ntseeg tau tias muaj qee qhov kev sib haum xeeb ntawm theem , raws li kev qhia kom paub tseeb tias cov cable khiav yog hluav taws xob sib luag.

Dab tsi yog capacitance effect?

Thaum ob lub tshuab hluav taws xob ntawm qhov sib txawv ntawm qhov sib txawv nyob ze ua ke, qhov hluav taws xob nruab nrab ntawm lawv ua rau cov nqi hluav taws xob khaws cia rau ntawm lawv; qhov no nyhuv yog parasitic capacitance.
