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

Options

A. 2H
B. 4H
C. 3H
D. 8H

Answer

A

Explanation

Change in magnetic flux `(phi)=2 xx 1^(-2) Wb ` and change in current (I)=0.01A.
Change in magnetic flux , `phi = 2 xx 10^(-2)=MI`
`=M xx 0.01 or M=( 2 xx 10^(-2))/(0.01)=2H` ( where M= coefficient of mutual inductance )
