In a coil, the current increases from 0 to 6 A in 0.4 s. If an induced of e.m.f of 15V is produced in the coil, then the coeffiecient of self-induction of the coil will be

A

0.5 H

B

0.75 H

C

1 H

D

1.5 H

Text Solution

Verified by Experts

The correct Answer is:
C
`e=L(dI)/(dt) :. 15 = L xx 6/0.4 :. L = 1H`.
