In figure the battery has a potential difference of `20 V`. Find

(a) the equivalent capacitance of all the capacitors across the battery and
(b) the charge stored on that, equivalent capacitance. Find the charge on
(c) capacitor 1,
(d) capacitor 2, and
(e) capacitor 3.

A

`20 muF`

B

`40 muF`

C

`10 muC`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
The circuit can be simplefied as follows:
.
Hence `C_(eq)=2 muF`. Thus, charge supplied by battery is `Q=2xx200=40 muC`.
Charge on required capacitor is `20 muC`.
