Question
A network of four capacitors of capacity equal to C1 = C,C = 2C,C3 = 3C and C4 = 4C are conducted to a batter as shown inthe figure. the ratio of the charges on C2 and C4 is


Options
A.4/7
B.3/22
C.7/4
D.22/3
Solution
Equivalent capacitance for three capacitors
(C1, C2 & C3) in series is given by

⇒ Ceq =
⇒ Ceq =
⇒ Charge on capacitors (C1, C2 & C3) in series
= CeqV =
Charge on capacitor C4 = C4V = 4CV

(C1, C2 & C3) in series is given by
⇒ Ceq =
⇒ Ceq =
⇒ Charge on capacitors (C1, C2 & C3) in series
= CeqV =

Charge on capacitor C4 = C4V = 4CV
