A coil has N turns and current passes through it is I ampere then we obtain L Henry of self inductance. Now if current is made doubled then new self inductance will be H.

Question

Accepted Answer

(2) L. Idea: self-inductance is a property of the coil alone, not of the current in it. For a solenoid L=(μ₀N²A)/ℓ: it is fixed by the turns, the area, the length and the core. Read from the definition L=(NΦ)/I: doubling I doubles the flux linkage NΦ too, so the ratio is unchanged. So the new self-inductance is still L henry.

A coil has N turns and current passes through it is I ampere then we obtain L Henry of self inductance. Now if current is made doubled then new self inductance will be ________ H.
