2. Umbuzo: Iyini ifomula yamandla agcinwe ku-capacitor?

Impendulo: Amandla (U) agcinwe ku-capacitor anikezwa yi- $U = 2 1 C V^{2}$ 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 eshajelwe 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 ukulimala noma umonakalo.

5. Umbuzo: Amandla agcinwe ku-capacitor ashintsha kanjani uma i-capacitance yehliswa ngesigamu ngenkathi igcina i-voltage ingaguquki?

Impendulo: Uma i-capacitance incishiswa phakathi futhi i-voltage ihlala ingaguquki, amandla agciniwe nawo azoncishiswa phakathi, njengoba amandla elingana ngqo ne-capacitance.

8. Umbuzo: I-capacitance iyonke ibalwa kanjani yama-capacitor axhunywe ngokufana?

Impendulo: Kuma-capacitor ahambisanayo, i-capacitance iyonke iyisamba se-capacitance ngayinye.

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 ebhethri bese inqanyulwa ngaphambi kokufinyelela ekushajeni okugcwele?

Impendulo: I-capacitor izogcina i-voltage eyayinayo ngesikhathi sokunqamuka futhi ngeke ishaje kakhulu ngaphandle kokuthi ixhunywe emuva emthonjeni wamandla.
