1. Ma capacitor anayi , C 1 = 2 μF, C 2 = 1 μF, C 3 = 3 μF, C 4 = 4 μF, alumikizidwa motsatizana. Dziwani mphamvu ya capacitor imodzi yomwe idzakhala ndi zotsatira zofanana ndi kuphatikiza.
Zodziwika:
Capacitor C 1 = 2 μ F
Capacitor C 2 = 1 μ F
Capacitor C 3 = 3 μ F
Capacitor C 3 = 4 μ F
Kufunidwa: Mphamvu yofanana
Yankho:
Mphamvu yofanana:
C = C 1 + C 2 + C 3
C = 4 μF + 2 μF + 3 μF = 9 μF
Mphamvu yofanana ya kuphatikiza konse ndi 9 μF.

2. Dziwani mphamvu ya capacitor C 2 ngati kusiyana komwe kungachitike pakati pa mfundo A ndi B ndi 9 Volts…
Zodziwika:
C apa c itor C 1 = 20 μ F = 20 x 10 -6 F
C apa c itor C 2 = 30 μ F = 30 x 10 -6 F
Kusiyana komwe kulipo pakati pa mfundo A ndi B (V AB ) = 9 Volts
Kufunidwa : mphamvu pa capacitor C2 ( Q2 )
Yankho:
Kusiyana komwe kungatheke:
Ma capacitor amalumikizidwa motsatizana kotero kuti kusiyana komwe kulipo pakati pa A ndi B (V AB ) = kusiyana komwe kulipo pa capacitor C 1 (V 1 ) = kusiyana komwe kulipo pa capacitor C 2 (V 2 ) = 9 Volts.
Chaja yamagetsi pa capacitor C2 :
Q 2 = C 2 V 2 = (30 x 10 -6 )(9) = 270 x 10 -6 C
Q 2 = 270 μC
Mphamvu yamagetsi pa capacitor C2 ndi 27 0 μ C.

3. Ma capacitor atatu , C 1 = 4 μF, C 2 = 2 μF, C 3 = 3 μF, alumikizidwa motsatizana. Ma capacitor ali ndi chaji. Kusiyana komwe kungatheke pa capacitor C 2 ndi 4 Volts. Dziwani
(a) Chaji yamagetsi pa ma capacitor C 1 , C 2 ndi C 3
(b) Mphamvu yamagetsi pa capacitor yofanana ndi ya kuphatikiza konse
Zodziwika:
C apa c itor C 1 = 4 μ F = 4 x 10 -6 F
C apacitor C 2 = 2 μ F = 2 x 10 -6 F
C apacitor C 3 = 3 μ F = 3 x 10 -6 F
Kusiyana komwe kungatheke pa capacitor C2 (V2 ) = 4 Volts
Kufunidwa : Chaji yamagetsi pa capacitor C3 ( Q3 )
Yankho:
(a) Chaji yamagetsi pa capacitor C3
Kusiyana komwe kungatheke pa capacitor C3 :
Ma capacitor amalumikizidwa motsatizana kotero kuti kusiyana komwe kungatheke pa capacitor C3 (V3) = kusiyana komwe kungatheke pa capacitor C2 (V2) = kusiyana komwe kungatheke pa capacitor C1 (V1) = kusiyana komwe kungatheke pa capacitor yofanana (V) = 4 Volt
Chaja yamagetsi pa capacitor C1 :
Q 1 = C 1 V 1 = (4 x 10 -6 )(4) = 16 x 10 -6 C
Q 1 = 16 μC
Chaja yamagetsi pa capacitor C2 :
Q 2 = C 2 V 2 = (2 x 10 -6 )(4) = 8 x 10 -6 C
Q 2 = 8 μC
Chaja yamagetsi pa capacitor C3 :
Q 3 = C 3 V 3 = (3 x 10 -6 )(4) = 12 x 10 -6 C
Q 3 = 12 μC
(b) Chaji yamagetsi pa capacitor yofanana
Q = Q 1 + Q 2 + Q 3
Q = 16 μ C + 8 μ C + 12 μ C = 36 μ C
Yankho lina:
Mphamvu yofanana:
C = C 1 + C 2 + C 3
C = 4 μF + 2 μF + 3 μF = 9 μF
C = 9 x 10 -6 F
Kusiyana komwe kungatheke pa capacitor yofanana:
V 1 = V 2 = V 3 = V = 4 Volt
Mphamvu yamagetsi pa capacitor yofanana:
Q = CV = (9 x 10 -6 )(4) = 36 x 10 -6 C
Q = 36 μC
