Reactance of a capacitor of capacitance ...

Reactance of a capacitor of capacitance `CmuF` for ac frequency `400/pi Hz` is `25 Omega` . The value C is

A

`50 mu F `

B

` 25 mu F `

C

` 100 mu F `

D

`75 mu F `

Verified by Experts

The correct Answer is:

A

`X_(C) = (1)/(2 pi fC)`
`rArr 25 = (1)/( 2 pi xx (400)/(pi) xx C) rArr C = (1)/(50 xx 400) = 50 mu F `
