In a solenoid, if number of turns per unit length is doubled, then self inductance will become: |
half of its initial value double of its initial value $\frac{1}{4}$ times of its initial value 4 times of its initial value |
4 times of its initial value |
The correct answer is Option (4) → 4 times of its initial value $Z×n^2$ $⇒Z×(2n)^2$ $⇒Z×4n$ hence, Z increased by 4 times. |
