If equivalent capacitance of given circuit is `15 mu F ` then C = ........ .
(a) `5 mu F `
(b) `35 mu F `
(c) `50 mu F `
(d) `60 mu F `

A

`5 mu F `

B

`35 mu F `

C

`50 mu F `

D

`60 mu F `

Text Solution

Verified by Experts

`(1)/(15)=(1)/(20)+(1)/(C)`
`:. (1)/(C)=(1)/(15)-(1)/(20)`
`:. (1)/(C)=(20-15)/(300)`
`:. (1)/(C)=(5)/(300)`
`:. (1)/(C)=(1)/(60)`
`:. C = 60 mu F`
