The core of a coil has a length of 10 cm. The self inductance is 8 mH. If the core length is doubled, all other quantities remaining the same, the self inductance will be
Options
A. 32 mH
B. 16 mH
C. 8 mH
D. 4 mH
Correct Answer
4 mH
Explanation
Inductance is inversely proportional to the core length.
