1. E toru ngā pūnga hiko, C 1 = 2 μF, C 2 = 4 μF, C 3 = 4 μF, e honoa ana i roto i te raupapa me te whakarara . Tātaihia te kaha o tētahi pūnga hiko kotahi ka rite te pānga ki te whakakotahitanga.
Mōhiotia:
Pūnga C 1 = 2 μ F
Pūnga C 2 = 4 μ F
Pūnga C 3 = 4 μ F
E hiahiatia ana: Te kaha ōrite (C)
Rongoā:
Ka honoa ngā pūnga C 2 me C 3 ki te taha whakarara. Ko te pūnga ōrite:
C P = C 2 + C 3 = 4 + 4 = 8 μ F
Ka honoa ngā pūnga C 1 me C p i roto i te raupapa. Ko te pūnga ōrite:
1/C = 1/C 1 + 1/ C P = 1/2 + 1/8 = 4 / 8 + 1/8 = 5/8
C = 8/5 μF

2. E rima ngā pūnga hiko, C 1 = 2 μF, C 2 = 4 μF, C 3 = 6 μF, C 4 = 5 μF, C 5 = 10 μF, kua honoa raupapa, kua honoa whakarara hoki. Tātaihia te kaha o tētahi pūnga hiko kotahi ka rite te pānga ki te whakakotahitanga.
Mōhiotia:
Pūnga C1 = 2 μF
Pūnga C 2 = 4 μ F
Pūnga C 3 = 6 μ F
Pūnga C 4 = 5 μ F
Pūnga C 5 = 10 μ F
E hiahiatia ana: Te kaha ōrite (C)
Rongoā:
Ka honoa ngā pūnga C 2 me C 3 ki te taha whakarara. Ko te pūnga ōrite:
CP = C2 + C3
CP = 4 + 6
CP = 10 μF
Ka honoa ngā pūnga hiko C1 , CP , C4 me C5 i roto i te raupapa. Ko te pūnga hiko ōrite:
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 μF

3 C1 = 3 μF, C2 = 4 μF me C3 = 3 μKo ngā F, he mea hono raupapa, he mea hono whakarara hoki. Whakatauhia te pūngao hiko i runga i te awheawhe.
Mōhiotia:
Pūnga C1 = 3 μF
Pūnga C 2 = 4 μ F
Pūnga C 3 = 3 μ F
E hiahiatia ana: Te kaha ōrite (C)
Rongoā:
Ka honoa ngā pūnga C 2 me C 3 ki te taha whakarara. Ko te pūnga ōrite:
CP = C2 + C3
CP = 4 + 3
CP = 7 μF
Ka honoa ngā pūnga C 1 me C P i roto i te raupapa. Ko te pūnga ōrite:
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 µF
C = 2.1 x 10 -6 F
Te pūngao hiko i runga i ngā ara iahiko:
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
