A long solenoid has `1000` turns. When a current of `4A` flows through it, the magnetic flux linked with each turn of the solenoid is `4xx10^(-3)Wb`. The self-inductance of the solenoid is

A

4 H

B

3 H

C

2 H

D

1 H

Text Solution

Verified by Experts

The correct Answer is:
D
Flux linked with each turn = `4xx10^(-3)Wb`
`therefore` Total flux linked = `1000[4xx10^(-3)]Wb`
`varphi_("total")=4rArrLi=4rArrL=1H`.
