A magnetic flux of `5xx10^(-1)wb` is associated with every 10 turns of a 500 turns coil. The electric current flowing through the wire is 5A. The self inductance of coil will be

A

`0.5H`

B

`5xx10^(-3)H`

C

`5H`

D

`5xx10^(-2)H`

Text Solution

Verified by Experts

The correct Answer is:
B
`phi =(5xx10^(-4))/(10)xx500=2.5xx10^(-2)wb`
`L=(phi)/(i)=5xx10^(-3)H`
