Two capacitors each of value C are connected in parallel. When this combination is connected in series with an identical combination, the effective capacitance becomes:

A

4C

B

2C

C

C/2

D

C

Text Solution

Verified by Experts

The correct Answer is:
D
`C+C=2C` in parallel.
`(1)/(C_(S))=(1)/(2C)+(1)/(2C)=(2)/(2C)=(1)/(C)` in series `therefore`Effective capacity=C.
