1. Umbuzo: Amandla agcinwa kanjani ku-capacitor?
Impendulo: Amandla ku-capacitor agcinwa ensimini kagesi phakathi kwamapuleti ayo. Uma i-voltage isetshenziswa ku-capacitor, amashaja amahle aqoqana epuletini elilodwa kanye namacala amabi epuletini eliphambene, okudala insimu kagesi.
2. Umbuzo: Iyini ifomula yamandla agcinwe ku-capacitor?
Impendulo: Amandla (U) agcinwe ku-capacitor anikezwa yi -�=12��2 lapho u-C eyi-capacitance kanti u-V uyi-voltage kuyo yonke i-capacitor.
3. Umbuzo: Kwenzekani kumandla agcinwe ku-capacitor uma i-voltage iphindwe kabili?
Impendulo: Njengoba amandla elingana nesikwele se-voltage (V^2), lapho i-voltage iphindwe kabili, amandla anda ngesilinganiso sesine.
4. Umbuzo: Kungani i-capacitor eshajiwe ingaba yingozi noma ngabe inqanyuliwe emthonjeni wayo we-voltage?
Impendulo: I-capacitor eshajiwe ingagcina amandla ayo agciniwe ngisho noma ingaxhunyiwe emthonjeni wayo we-voltage. Uma umqhubi (noma umuntu) ethinta ama-terminal, amandla agciniwe angakhishwa ngokushesha, okungase kubangele umonakalo noma umonakalo.
5. Umbuzo: Amandla agcinwe ku-capacitor ashintsha kanjani uma i-capacitance yehliswa phakathi ngenkathi igcina i-voltage ingaguquki?
Impendulo: Uma i-capacitance ihlukaniswa phakathi futhi i-voltage ihlala ingaguquki, amandla agciniwe nawo azohlukaniswa phakathi, njengoba amandla elingana ngqo ne-capacitance.
6. Umbuzo: Iyiphi indima edlalwa yizinto ze-dielectric ku-capacitor?
Impendulo: Izinto ze-dielectric zandisa amandla e-capacitor ngokunciphisa insimu kagesi esebenzayo phakathi kwamapuleti futhi zivimbela nokuqhutshwa kweshaja phakathi kwamapuleti.
7. Umbuzo: Kusekhethi ye-capacitor yochungechunge, i-capacitance iyonke iqhathaniswa kanjani ne-capacitance ngayinye?
Impendulo: Kuhlelo lochungechunge, ukuphambuka kwe-capacitance iyonke (1/C_total) kuyisamba sokuphambuka kwe-capacitance ngayinye. Lokhu kusho ukuthi i-capacitance iyonke ekucushweni kochungechunge ihlala ingaphansi kwe-capacitance encane kakhulu ochungechungeni.
8. Umbuzo: I-capacitance iyonke ibalwa kanjani yama-capacitor axhunywe ngokulingana?
Impendulo: Kuma-capacitor ahambisanayo, i-capacitance iyonke iyisamba sama-capacitance ngamanye.
9. Umbuzo: Kungani i-capacitor ivimba umugqa wamanje (DC) kodwa ivumele umugqa wamanje oshintshanayo (AC) ukuthi udlule?
Impendulo: I-capacitor ivimba i-DC ngoba uma isishajwe ngokugcwele, awekho amanye amandla kagesi angageleza. Kodwa-ke, nge-AC, i-voltage ishintsha njalo, okubangela ukuthi i-capacitor ishaje futhi ikhiphe, okuvumela ukuthi kugeleze amandla kagesi asebenzayo.
10. Umbuzo: Kwenzekani ku-voltage ye-capacitor uma ixhunywe ebhethrini bese inqanyulwa ngaphambi kokuba ifike ekushajeni okugcwele?
Impendulo: I-capacitor izogcina i-voltage eyayinayo ngesikhathi sokunqanyulwa futhi ngeke ishaje kakhulu ngaphandle kokuthi ixhunywe emuva emthonjeni wamandla.
