Can we use a DC source with an inductor?

Answer 1

Yes, an inductor allows DC to pass through it.

An inductor resists a change in current, proportional to inductance and voltage. At equilibirum, an ideal inductor has zero impedance.

The differential equation for an inductor is di/dt = v / l

Answer 2

Yes, DC does indeed pass through an inductor. To a DC source, an inductor is like a straight peice of wire. Inductors store energy in their magnetic field. A change in the current flow through them causes a partial current opposite the direction of the source current.

Answer 3

Yes,you can use dc supply in an inductor.when you give a dc supply to an inductor or a coil,then ultimately you are creating a field,but remember one thing while giving the supply,the current supplied to the inductor should be less in order to avoid burn out of the coil.when you are giving a dc supply the resistance only comes into effect not the reactance.

In case of AC,the inductor behaves in a different manner,when you give an ac supply,which is not constant in magnitude,the inductor will always oppose the change in magnitude and ultimately will induce an emf according to lenz's law.if a complete path is provided for the circuit then the emf induced will make the current to flow.
