Answer / kannu

Inductane of coil is given by l=flux linkage/current
through coil.
As current through coil increases saturation may set in and
corresponding change in flux might be less, this leads to
decrease in inductance of the coil.

Answer / balaji

inductance of coil depends on number of turns of the coil.if
turns vary,resistance will defenitly vary,so current changes
and viceversa
