The coefficient of mutual inductance when magnetic flux change by `2xx10^(-2)Wb` and current changes by `0.01A`, will be

A

`4H`

B

`3H`

C

`8H`

D

`2H`

Text Solution

Verified by Experts

The correct Answer is:
D
Coefficient of mutual induction of two coils is equal to the number of magnetic flux `(phi)` linkages in one coil when a unit current (i) flows in the other.
therefore, `M=(phi)(i)`
Given, `phi=2xx10^(-2)Wb,i=0.01A`
`:. M=(2xx10^(-2))/(0.01)=2H`
