Explain why inductance of the iron cored coil changes with
current?
Answer Posted / 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.

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
