A long solenoid has `500` turns. When a current of `2A` is passed through it, the resulting magnetic flux linked with each turn of the solenoid is `4xx10^(-3)Wb` . The self-inductance of the solenoid is

A

1.0 henry

B

4.0 henry

C

2.5 henry

D

2.0 henry

Text Solution

Verified by Experts

The correct Answer is:
A
`N=500,i=2A,varphi=4xx10^(-3)`
Since, `Nvarphi=Li`
`rArrL=(500xx4xx10^(-3))/2=1H`.
