An inductive circuit a resistance of `10ohm` and an inductance of `2.0` henry. If an AC voltage of `120`volt and frequency of `60Hz` is applied to this circuit, the current in the circuit would be nearly

A

`0.32 amp`

B

`0.16 amp`

C

`0.48 amp`

D

`0.80 amp`

Text Solution

Verified by Experts

The correct Answer is:
B
`Z=sqrt(R^(2)+X_(L)^(2))=sqrt(10^(2)+(2pixx60xx2)^(2))=0.016A`
`:. i=120/753.7=0.159A`
