Potential difference between A and B is ...

Potential difference between A and B is 50 V. Then, potential difference across `6 muF` capacitor is:

A

`7.2 V`

B

`8.3 V`

C

`9.2 V`

D

`5.5 V`

Text Solution

Verified by Experts

The correct Answer is:
b
From the given figure, `3 muF` and `3 muF` are in parallel and their equivalent capacitance is `6 muF`.
The equivalent circuit now reduced to

The equivalent capacitance between A and B is
`1/C = 1/6 + 1/3 + 1/6 + 1/3`
or `C = 1 mu F`
Now, charge in the circuit,
`Q = CV = (1 mu F) xx (50 V)`
`= 50 mu C`
Potential difference across `6 muF` capacitor
` = (50 mu C)/(6 mu F)`
`= 8.3 V`
