Contoh soal
1. Tiga kapasitor masing-masing berkapasitas 2 µF, 3

µF, dan 4 µF disusun seri, kemudian diberi sumber
listrik 13 volt. Tentukan potensial listrik masing-
masing kapasitor?

Diketahui : C1 = 2 µF = 2 × 10 F
-6
C2 = 3 µF = 3 × 10 F
-6
C3 = 4 µF = 4 × 10 F
-6
V = 13 Volt
Ditanya : V1, V2, V3 ?

Jawab?

C 1 C 2 C 3

V 1 V 2 V 3

E

= 13 = 13 × 10
12 −6 −6
= ∙ = 13 × 10 ∙ 13 = 12 × 10

= 1 = 12×10 −6 = 6
