A) be halved
B) remain un change
C) be doubled
D) become four times
Correct Answer: D
Solution :
Self-inductance of solenoid \[=\,\,\,\mu {{n}^{2}}\,Al\] n : number of turns per unit length \[\operatorname{Self}-induction\,\,\propto {{n}^{2}}\] So, inductance becomes 4 times when n is doubled.You need to login to perform this action.
