Hint: Here it is stated in the question what would be the consequences when an inductor is used in D.C. power supply. So, we have to understand what is meant by an inductor and also what are the characteristics of a D.C. current supply.
Complete answer:
We have to first understood what an inductor refers to. An inductor is an electrical component that is used in most power electronic circuits to store energy in the form of magnetic energy when current electricity is applied to it.
The main function of an inductor is that it impedes or opposes any change in the amount of current flowing through it. Whenever the current across the inductor changes it either acquires charge or loses the charge in order to equalize the current passing through it. The inductor is also called a choke, reactor or just coil.
D.C. current refers to direct current where there is no change in the direction of current with respect to time.
Therefore, we got to find out that inductor works on the principle of changing electric flux. When D.C. current is used then there is no change in magnetic flux as D.C. does not have any zero frequency. Hence, it will work as a short-circuit or a connecting wire with no resistance when D.C. current is used.
Note: Inductors are mainly used in A.C. circuits. It is used mainly to control or decrease current without any loss of power. Inductive reactance acts on the inductor when worked in an A.C. circuit.
