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

A

`(2)/(5)H`

B

`(4)/(5)H`

C

`(5)/(4)H`

D

1/2 H

Text Solution

Verified by Experts

The correct Answer is:

D

Self-inductance of coil,
`|e|=L(di)/(dt)`
`therefore" "20=Lxx(10)/(1)`
`therefore"Self inductance,"L=1/2H`
