The outer cylinders of two cylindrical capacitors of capacitance 2mF each are kept in contact and the inner cylinders are connected through a wire. A battery of emf 8 V is connected. The total charge supplied by battery-
A
q = 2mC
B
q = 8mC
C
q = 16mC
D
q =332mC
Answer
q =332mC
Explanation
Solution
Ceq = C1 + C2 = 2+ 2 = 4mF
q = Ceq V = 4mF × 8 = 32mq
