A `120` volt `AC` source is connected across a pure inductor of inductance `0.70` henry. If the frequency of the source is `60Hz`, the current passing through the inductor is

A

`4.55 A`

B

`0.355 A`

C

`0.455 A`

D

`3.55 A`

Text Solution

Verified by Experts

The correct Answer is:
3
`X_(L) = 2 pi fl = 6.28 xx 60 xx 0.70 = 263.76 Omega`
`I = (V)/(X_(L)) = (120)/(263.76) = 0.455 A`
