The total number of turns and cross-section area in a solenoid is fixed. However, its length L is varied by adjusting the separation between windings. The inductance of solenoid will be proportional to :

A

`L^(2)`

B

`1//L^(2)`

C

L

D

`1//L`

Text Solution

Verified by Experts

The correct Answer is:

D

For a solenoid, self inductance is given as
`L_("self")=NxxAxx mu_(0)(N/L) :. L_("self") prop 1/L`
