2. Whakahuahia te tenei i runga i te pūngahiko C2 ki te rerekētanga pūmanawa kei waenganui i te pūwāhi A me te pūwāhi B 9 Ngā Waohiko…
Mōhiotia:
Cahacitor C1 = 20 μF = 20 x 10-6 F
Cahacitor C2 = 30 μF = 30 x 10-6 F
Te rerekētanga pūmanawa i waenga i ngā pūwāhi A a B (VAB) = 9 Ngāohiko
hiahia : te utu i runga i te pūnga C2 (Q2)
Rongoā:
Rerekētanga pūmanawa:
Ka honoa ngā pūnga iahiko i roto i te whakarara kia rite ai te rerekētanga pūmanawa i waenga i a A me B (V)AB) = te rerekētanga pūmanawa i runga i te pūnga C1 (V1) = te rerekētanga pūmanawa i runga i te pūnga C2 (V2) = 9 Ngā Āhuatanga.
Utu hiko i runga i te pūnga C2 :
Q2 = C2 V2 = (30 x 10-6)(9) = 270 x 10-6 C
Q2 = 270 μC
Te utu hiko i runga i te pūnga C2 is 270 μC.
3. e toru ngā pūnga iahiko, C1 = 4 µF, C2 = 2 µF, C3 = 3 μF, e honoa ana i te taha whakarara. Ka utua ngā pūnga. Ko te rerekētanga pūmanawa i runga i te pūnga C2 he 4 Volts. Whakatauhia
(a) Utu hiko i runga i te pūnga C1, C2 me C3
(b) Te utu hiko i runga i te pūnga rite o te huinga katoa
Mōhiotia:
Cahacitor C1 = 4 μF = 4 x 10-6 F
Cpūnga iahiko C2 = 2 μF = 2 x 10-6 F
Cpūnga iahiko C3 = 3 μF = 3 x 10-6 F
Te rerekētanga pūmanawa i runga i te pūnga C2 (V2) = 4 Ngāohiko
hiahia : Utu hiko i runga i te pūnga C3 (Q3)
Rongoā:
(a) Utu hiko i runga i te pūnga C3
Te rerekētanga pūmanawa i runga i te pūnga C3 :
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
Utu hiko i runga i te pūnga C1 :
Q1 = C1 V1 = (4 x 10-6)(4) = 16 x 10-6 C
Q1 = 16 μC
Utu hiko i runga i te pūnga C2 :
Q2 = C2 V2 = (2 x 10-6)(4) = 8 x 10-6 C
Q2 = 8 μC
Utu hiko i runga i te pūnga C3 :
Q3 = C3 V3 = (3 x 10-6)(4) = 12 x 10-6 C
Q3 = 12 μC
(B) Utu hiko i runga i te pūnga rite
Q = Q1 +Q2 +Q3
Q = 16 μC + 8 μC + 12 μC=36 μC
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:
V1 =V2 =V3 = 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
