If a current of 10 A changes in one second throught a coil, and the induced emf is 20 V, then the self-inductance of the coil is

A

`2/5 H`

B

`4/5`H

C

`5/4H`

D

1H

Text Solution

Verified by Experts

The correct Answer is:

D

(4) : Self inductance of coil
`|e|=L(di)/(dt),:.10=Lxx10/1`
`:.L=1H`
