The reactance of a coil when used in the domestic AC power supply `(220V,50cycl es)` is `50ohm`. The inductance of the coil is nearly

A

2.2 H

B

1.6 H

C

0.22 H

D

0.16 H

Text Solution

Verified by Experts

The correct Answer is:
D
`underset(L)(X)` = (`2pi`fL)
`therefore` L = `underset(L)(X)` / `2pi`f = 50 / `(2pi)`(50) = 0.16 H
