1. E whā ngā pūnga hiko , C 1 = 2 μF, C 2 = 1 μF, C 3 = 3 μF, C 4 = 4 μF, e honoa ana i te taha whakarara. Tātaihia te kaha o tētahi pūnga hiko kotahi ka rite te pānga ki te huinga.
Mōhiotia:
Pūnga C 1 = 2 μ F
Pūnga C 2 = 1 μ F
Pūnga C 3 = 3 μ F
Pūnga C 3 = 4 μ F
E hiahiatia ana: Te kaha ōrite
Rongoā:
Te kaha ōrite:
C = C1 + C2 + C3
C = 4 μF + 2 μF + 3 μF = 9 μF
Ko te kaha ōrite o te huinga katoa ko 9 μF.

2. Tāutuhia te utu i runga i te pūnga C 2 mēnā ko te rerekētanga pūmanawa i waenga i ngā pūwāhi A me B he 9 Volts…
Mōhiotia:
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
Te rerekētanga pūmanawa i waenga i ngā pūwāhi A me B (V AB ) = 9 Volts
E hiahiatia ana : te utu i runga i te pūnga C 2 (Q 2 )
Rongoā:
Rerekētanga pūmanawa:
Ka honoa ngā pūnga hiko i te taha whakarara kia rite ai te rerekētanga pūmanawa i waenga i a A me B (V AB ) = te rerekētanga pūmanawa i runga i te pūnga hiko C 1 (V 1 ) = te rerekētanga pūmanawa i runga i te pūnga hiko C 2 (V 2 ) = 9 Volts.
Te utu hiko i runga i te pūnga C 2 :
Q 2 = C 2 V 2 = (30 x 10 -6 )(9) = 270 x 10 -6 C
Q 2 = 270 μC
Ko te utu hiko i runga i te pūnga C 2 he 27 0 μC.

3. E toru ngā pūnga hiko, C 1 = 4 μF, C 2 = 2 μF, C 3 = 3 μF, e honoa ana i te taha whakarara. Ka utaina ngā pūnga hiko. Ko te rerekētanga pūmanawa i runga i te pūnga hiko C 2 he 4 Volts. Whakatauhia
(a) Te utu hiko i runga i ngā pūnga hiko C 1 , C 2 me C 3
(b) Te utu hiko i runga i te pūnga rite o te huinga katoa
Mōhiotia:
C apa c itor C 1 = 4 μ F = 4 x 10 -6 F
Pūhiko C 2 = 2 μ F = 2 x 10 -6 F
Pūhiko C 3 = 3 μ F = 3 x 10 -6 F
Te rerekētanga pūmanawa i runga i te pūnga C 2 (V 2 ) = 4 Volts
E hiahiatia ana : Te utu hiko i runga i te pūnga C 3 (Q 3 )
Rongoā:
(a) Te utu hiko i runga i te pūnga C 3
Te rerekētanga pūmanawa i runga i te pūnga C 3 :
Ka honoa ngā pūnga iahiko i te taha whakarara kia puta ai te rerekētanga pūmanawa i runga i te pūnga iahiko C3 (V3) = te rerekētanga pūmanawa i runga i ngā pūnga C2 (V2) = te rerekētanga pūmanawa i runga i ngā pūnga C1 (V1) = te rerekētanga pūmanawa i runga i ngā pūnga taurite (V) = 4 Ngāohiko
Te utu hiko i runga i te pūnga C 1 :
Q 1 = C 1 V 1 = (4 x 10 -6 )(4) = 16 x 10 -6 C
Q 1 = 16 μC
Te utu hiko i runga i te pūnga C 2 :
Q 2 = C 2 V 2 = (2 x 10 -6 )(4) = 8 x 10 -6 C
Q 2 = 8 μC
Te utu hiko i runga i te pūnga C 3 :
Q 3 = C 3 V 3 = (3 x 10 -6 )(4) = 12 x 10 -6 C
Q 3 = 12 μC
(b) Utu hiko i runga i te pūnga rite
Q = Q1 + Q2 + Q3
Q = 16 μ C + 8 μ C + 12 μ C = 36 μ C
Otinga kē atu:
Te kaha ōrite:
C = C1 + C2 + C3
C = 4 μF + 2 μF + 3 μF = 9 μF
C = 9 x 10 -6 F
Te rerekētanga pūmanawa i runga i te pūnga taurite:
V 1 = V 2 = V 3 = V = 4 Ngāohiko
Ko te utu hiko i runga i te pūnga rite:
Q = CV = (9 x 10 -6 )(4) = 36 x 10 -6 C
Q = 36 µC
