A coil of `N=100` turns and area `1cm^2` carries a current `I=5 A` and creates a magnetic flux `varphi=10^(-5)Tm^(-2)` .The value of its inductance `L` will be

A

0.05 mH

B

0.10 mH

C

0.15 mH

D

0.20 mH

Text Solution

Verified by Experts

The correct Answer is:
D
`N phi = Li rArr L=(N phi)/(i)=(100xx10^(-5))/(5)=0.20 mH`
