1. Vipokezi vitatu, C 1 = 2 μF, C 2 = 4 μF, C 3 = 4 μF, vimeunganishwa mfululizo na sambamba . Tambua uwezo wa kipokezi kimoja ambacho kitakuwa na athari sawa na mchanganyiko.
Inajulikana:
Kifaa cha kupokanzwa C 1 = 2 μ F
Kifaa cha kupokanzwa C 2 = 4 μ F
Kifaa cha kupokanzwa C 3 = 4 μ F
Inayohitajika: Uwezo sawa (C)
Suluhisho:
Vipokea sauti C2 na C3 vimeunganishwa sambamba. Uwezo sawa:
C P = C 2 + C 3 = 4 + 4 = 8 μ F
Vipokeaji C 1 na C p vimeunganishwa mfululizo. Uwezo sawa:
1/C = 1/C 1 + 1/ C P = 1/2 + 1/8 = 4/8 + 1/8 = 5/8
C = 8/5 μ F
2. Vipokezi vitano , C 1 = 2 μF, C 2 = 4 μF, C 3 = 6 μF, C 4 = 5 μF, C 5 = 10 μF, vimeunganishwa mfululizo na sambamba. Tambua uwezo wa kipokezi kimoja ambacho kitakuwa na athari sawa na mchanganyiko.
Inajulikana:

Kifaa cha kupokanzwa C 5 = 10 μ F
Inayohitajika: Uwezo sawa (C)
Suluhisho:
Vipokea sauti C2 na C3 vimeunganishwa sambamba. Uwezo sawa:
CP = C 2 + C 3
CP = 4 + 6
CP = 10 μ F
Vipokeaji vikubwa C 1 , C P , C 4 na C 5 vimeunganishwa mfululizo. Uwezo sawa:
1/C = 1/C 1 + 1/ C P + 1/ C 4 + 1/ C 5
1 /C = 1/2 + 1/10 + 1/5 + 1/10
1/C = 5/10 + 1/10 + 2/10 + 1/10
1/C = 9/10
C = 10/9 μ F
3 C1 = 3 μF, C2 = 4 μF na C3 = 3 μF, zimeunganishwa katika mfululizo na sambamba. Amua nishati ya umeme juu ya nyaya.
Inajulikana:
Kifaa cha Kuhifadhia Mizigo C1 = 3 μF
Kifaa cha kupokanzwa C 2 = 4 μ F
Kifaa cha kupokanzwa C 3 = 3 μ F
Inayohitajika: Uwezo sawa (C)
Suluhisho:
Vipokea sauti C 2 na C 3 vimeunganishwa sambamba. Uwezo sawa:
CP = C 2 + C 3
CP = 4 + 3
CP = 7 μ F
Vipokeaji C 1 na C P vimeunganishwa mfululizo. Uwezo sawa:
1/C = 1/C 1 + 1/ C P
1/C = 1/3 + 1/7
1/C = 7/21 + 3/21
1/C = 10/21
C = 21/10
C = 2.1 μ F
C = 2.1 x 10 -6 F
Nishati ya umeme kwenye saketi:
E = ½ CV 2
E = ½ ( 2.1 x 10 -6 )(12 2 )
E = ½ (2.1 x 10 -6 ) (144)
E = (2.1 x 10 -6 )(72)
E = 151.2 x 10 -6 Joule
E = 1.5 x 10 -4 Joule
