Yog tias tus neeg coj hluav taws xob (lossis ib tus neeg) kov cov terminals, lub zog khaws cia tuaj yeem tso tawm sai sai, uas ua rau muaj kev phom sij lossis kev puas tsuaj.
5. Lo lus nug: Lub zog khaws cia rau hauv lub capacitor hloov li cas yog tias lub capacitance raug ib nrab thaum khaws cia qhov voltage tas li?
Lus Teb: Yog tias lub capacitance raug txiav ib nrab thiab qhov voltage tseem ruaj khov, lub zog khaws cia kuj yuav raug txiav ib nrab, vim tias lub zog yog proportional ncaj qha rau lub capacitance.
6. Lo lus nug: Lub luag haujlwm ntawm cov khoom siv dielectric ua si hauv lub capacitor yog dab tsi?
Lus Teb: Cov khoom siv dielectric ua rau lub capacitance ntawm lub capacitor nce ntxiv los ntawm kev txo qhov hluav taws xob zoo ntawm cov phaj thiab tseem tiv thaiv kev them nqi ntawm cov phaj.
7. Lo lus nug: Hauv ib lub voj voog capacitor series, tag nrho cov capacitance piv rau cov capacitances ntawm tus kheej li cas?
Lus Teb: Hauv kev teeb tsa ua ke, qhov tig rov qab ntawm tag nrho cov capacitance (1 / C_total) yog qhov sib npaug ntawm cov tig rov qab ntawm cov capacitances ib leeg. Qhov no txhais tau tias tag nrho cov capacitance hauv kev teeb tsa ua ke yeej ib txwm tsawg dua li qhov capacitance me tshaj plaws hauv cov koob.
8. Lo lus nug: Tag nrho cov peev xwm suav rau cov capacitors txuas nrog parallel li cas?
Lus Teb: Rau cov capacitors hauv parallel, tag nrho cov capacitance yog qhov sib sau ua ke ntawm cov capacitances ib tus zuj zus.
9. Lo lus nug: Vim li cas lub capacitor thaiv cov hluav taws xob ncaj qha (DC) tab sis cia cov hluav taws xob hloov pauv (AC) hla dhau?
Lus Teb: Lub capacitor thaiv DC vim tias thaum nws them tag lawm, tsis muaj hluav taws xob ntxiv tuaj yeem ntws mus. Txawm li cas los xij, nrog AC, qhov hluav taws xob hloov pauv tas li, ua rau lub capacitor them thiab tso tawm, ua rau muaj hluav taws xob zoo ntws mus.
10. Lo lus nug: Ua li cas rau lub capacitor qhov voltage yog tias nws txuas nrog lub roj teeb thiab tom qab ntawd txiav tawm ua ntej mus txog qhov them tag nrho?
Lus Teb: Lub capacitor yuav khaws cov voltage uas nws muaj thaum lub sijhawm txiav tawm thiab yuav tsis them ntxiv tshwj tsis yog txuas rov qab rau lub zog fais fab.
