If a current of 3A, flowing in the primary coil is reduced to zero in `10^(-3) s`, the induced e.m.f in the secondary coil is 15000 V. The mutual inductance between the two coils is

A

5 H

B

10 H

C

0.5 H

D

2.5 H

Text Solution

Verified by Experts

The correct Answer is:
A
`e_(s) = M(dI_p)/(dt) :. 15000 = M xx 3xx10^(3) :. M = 5 H`
