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 amps`

B

`0.355 amps`

C

`0.455 amps`

D

`3.55 amps`

Text Solution

Verified by Experts

The correct Answer is:
C
`Z=X_(L)=2pixx60xx0.7`
`:. i=120/Z=120/(2pixx60xx0.7)=0.455 ampere`
