Three capacities of respective capacities 6, 4 and `2muF` are connected in parallel and P.D. of 5 volt applied across it. Its total capacity and the charge on each condenser in order will be

A

`12muF, 30muC, 10muC, 20muC`

B

`12muF, 10muC, 30muC, 20muC`

C

`12muF, 10muC, 20muC, 30muC`

D

`12muF, 30muC, 20muC, 10muC`

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(P)=C_(1)+C_(2)+C_(3)=6+4+2=12muF`
`Q_(1)=C_(1)V=6xx5=30muC`
`Q_(2)=C_(2)V=4xx5=20muC`
`Q_(3)=C_(3)V=2xx5=10muC`
