The reactance of an inductor at 50 Hz is...

The reactance of an inductor at 50 Hz is `100Omega`. If the frequency is increased to 60 Hz, the reactance of the same inductor becomes

A

`12Omega`

B

`21 Omega`

C

`1.2Omega`

D

`120Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
`(X_(L1))/(X_(L2))=(f_(1))/(f_(2))=(50)/(60)`
`therefore X_(L2)=(f_(2))/(f_(1))X_(L1)=120Omega`
