The capacitive reactance is `20Omega`, when the frequency is 100 Hz. Find the reactance, when frequency is 150 Hz.

A

`13Omega`

B

`12.5Omega`

C

`12.3Omega`

D

`13.3Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
`X prop (1)/(f)`
`therefore (X_(2))/(X_(1))=(f_(1))/(f_(2))`
`X_(2)=(100)/(150)xx20=13.3Omega`
