1. Okune capacitors, C1 = 2 μF, C2 = 1 μF, C3 = 3 μF, C4 = 4 μF, zixhunywe ngokulingana. Thola amandla e-capacitor eyodwa azoba nomphumela ofanayo nenhlanganisela.
Kwaziwa:
Umshayeli wemisebenzi C1 = 2 μF
Umshayeli wemisebenzi C2 = 1 μF
Umshayeli wemisebenzi C3 = 3 μF
Umshayeli wemisebenzi C3 = 4 μF
Kufunwa: I-capacitance elinganayo
Isixazululo:
I-capacitance efanayo:
C = C1 + C.2 + C.3
C = 4 μF+2 μF+3 μF=9 μF
I-capacitance elinganayo yenhlanganisela yonke ingu-9 μF.
2. Nquma i- ukukhokha ku-capacitor C2 uma i umehluko ongaba khona phakathi kwephuzu A no-B Ama-volt angu-9…
Kwaziwa:
Claphacu-C1 = 20 μF = 20 x 10-6 F
Claphacu-C2 = 30 μF = 30 x 10-6 F
Umehluko ongaba khona phakathi kwamaphuzu A futhi B (V)AB) = 9 Volt
wayefuna : ukushaja ku-capacitor C2 (Q2)
Isixazululo:
Umehluko ongaba khona:
Ama-capacitor axhunywe ngasikhathi sinye ukuze umehluko ongaba khona phakathi kuka-A no-B (V)AB) = umehluko ongaba khona ku-capacitor C1 (V1) = umehluko ongaba khona ku-capacitor C2 (V2) = 9 Volts.
Ukushaja kukagesi ku-capacitor C2 :
Q2 = C2 V2 = (30 x 10-6)(9) = 270 x 10-6 C
Q2 = 270 μC
Ishaja kagesi ku-capacitor C2 is 270 μC.
3. Three ama-capacitor, C1 = 4 μF, C2 = 2 μF, C3 = 3 μF, zixhunywe ngokulingana. Ama-capacitor ayashajwa. Umehluko ongaba khona kuma-capacitor C2 yi-4 Volts. Thola
(a) Ukushaja kukagesi ku-capacitor C1, C2 no-C3
(b) Ukushaja kukagesi ku-capacitor elinganayo yenhlanganisela yonke
Kwaziwa:
Claphacu-C1 = 4 μF = 4 x 10-6 F
Ci-capacitor C2 = 2 μF = 2 x 10-6 F
Ci-capacitor C3 = 3 μF = 3 x 10-6 F
Umehluko ongaba khona ku-capacitor C2 (V2) = 4 Volt
wayefuna : Ukushaja kukagesi ku-capacitor C3 (Q3)
Isixazululo:
(A) Ukushaja kukagesi ku-capacitor C3
Umehluko ongaba khona kuma-capacitor C3 :
Ama-capacitor axhunywe ngokufana ukuze umehluko ongaba khona ku-capacitor C3 (V3) = umehluko ongaba khona ku-capacitor C2 (V2) = umehluko ongaba khona ku-capacitor C1 (V1) = umehluko ongaba khona ku-capacitor elinganayo (V) = 4 Volt
Ukushaja kukagesi ku-capacitor C1 :
Q1 = C1 V1 = (4 x 10-6)(4) = 16 x 10-6 C
Q1 = 16 μC
Ukushaja kukagesi ku-capacitor C2 :
Q2 = C2 V2 = (2 x 10-6)(4) = 8 x 10-6 C
Q2 = 8 μC
Ukushaja kukagesi ku-capacitor C3 :
Q3 = C3 V3 = (3 x 10-6)(4) = 12 x 10-6 C
Q3 = 12 μC
(B) Ukushaja kukagesi ku-capacitor elinganayo
Q = Q1 +Q2 +Q3
Q = 16 μC + 8 μC + 12 μC=36 μC
Isixazululo esihlukile:
I-capacitance efanayo:
C = C1 + C.2 + C.3
C=4 μF+2 μF+3 μF=9 μF
C = 9 x 10-6 F
Umehluko ongaba khona ku-capacitor efanayo:
V1 =V2 =V3 = V = 4 Volt
Ishaja kagesi ku-capacitor efanayo:
Q = I-CV = (9 x 10)-6)(4) = 36 x 10-6 C
Q = 36 μC
