An inductor of 30 mH is connected to a 220 V, 100 Hz ac source. The inductive reactance is

A

`10.58 Omega`

B

`12.64 Omega`

C

`18.85 Omega`

D

`22.67 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `L=30 mH=30xx10^(-3)H`
`V_("rms")=220V, upsilon = 100 Hz`
Inductive reactance,
`X_(L)=2pi upsilon L=2xx3.14xx100xx30xx10^(-3)=18.85 Omega`
