A) its length
B) the number of turns
C) the resistance of the coil
D) the square of the number of turns
Correct Answer: D
Solution :
From the relation \[l={{\mu }_{0}}{{n}^{2}}lA\] \[\Rightarrow \] \[L={{\mu }_{0}}\frac{{{N}^{2}}}{l}A\] \[\left( \because n=\frac{N}{l} \right)\] \[\Rightarrow \] \[L\propto {{N}^{2}}\]You need to login to perform this action.
