A coil of wire of a certain radius has `600` turns and a self-inductance of `108 mH`. The self-inductance of a `2^(nd)` similar coil of `500` turns will be

A

25 mH

B

50 mH

C

7.5 mH

D

75 mH

Text Solution

Verified by Experts

The correct Answer is:
D
`L prop N^(2)" "therefore (L_(2))/(L_(1))=((N_(2))/(N_(1)))^(2)`
`therefore L_(2)=75mH`
