An e.m.f. of `100` millivolts is induced in a coil when the current in another nearby coil becomes `10` ampere from zero in `0.1` second. The coefficient of mutual induction between the two coils will be

A

`1` millihenry

B

`10` millihenry

C

`100` millihenry

D

`1000` millihenry

Text Solution

Verified by Experts

The correct Answer is:
A
Induced e.mf. `e=M(di)/(dt)implies100xx10^(-3)=M((10)/(0.1))`
`:. M=10^(-3)H=mH`
