Inductor used in DC circuits is for safety purpose. When
inductor is connected on DC circuit storing and decaying is
happend in specific conditions.
when current suddenly increases then inductor produces self
induced emf opposing the current then voltage across L is
-Vemf. and when current becomes stable inductor will not
oppose the current and voltage acreoss the inductor is zero
and act like a normal wire or just shorted since freq in DC
is zero.
so final thing is, inductor will not allow the changes of
current in DC circuits

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
