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

`1H`

B

`4H`

C

`3H`

D

`2H`

Text Solution

Verified by Experts

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