A change in current through an inductor will induce a voltage into that conductor, the direction of which will always oppose that change in current. This is a natural phenomenon due to the conservation of energy.

What is the maximum inductor voltage when the inductor current is decreasing?
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
Why does an inductor block AC but allow DC?
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
An inductor is a device that opposes the?
An inductor is a passive electronic component that opposes changes in current flow through it. It accomplishes this by inducing a voltage that is proportional to the rate of change of current passing through it. The main property of an inductor is its inductance, which is a measure of its ability to store energy in a magnetic field. As a result, an inductor opposes changes in current by generating a back electromotive force (EMF) in the opposite direction of the applied voltage. This opposition to changes in current is often referred to as inductive reactance. Specifically, an inductor opposes: Changes in Current: When an electric current through an inductor increases, the inductor creates a magnetic field that stores energy. This energy is released when the current decreases, which opposes the decrease in current. Similarly, when the current decreases, the inductor generates a voltage to maintain the current flow, opposing the change. Alternating Current (AC): In an AC circuit, the current periodically changes direction. An inductor resists these changes and limits the rate at which the current can change. It effectively smoothens out variations in the current and behaves as a low-pass filter, allowing lower frequency components to pass while attenuating higher frequency components. Voltage Transients: Inductors also oppose sudden changes in voltage, commonly known as voltage transients or spikes. When a sudden voltage change occurs, the inductor generates an opposing voltage to mitigate the effect of the transient and limit the rate of change of the current. In practical applications, inductors are used in various electronic systems and devices. They are employed in power supplies, signal filtering circuits, motor control circuits, transformers, and many other applications where controlling current, energy storage, and voltage regulation are important.

What is the difference between an inductor and a capacitor?
Firstly the suffix '-ance' in each of those three words indicate the properties the material exhibits. Therefore resistance is the property by which any material tends to oppose the flow of current through it. Inductance is the property by which a material opposes the change in current, or opposes an alternating current. An inductor can be appreciated simply using a coil of insulated wire, or a solenoid. Capacitance is the property by which a material opposes the change in voltage across its ends, ie how it opposes alternating voltage. A capacitor comprises of, essentially, two metallic plates separated by a dielectric (a medium which may/may not be non-conducting, but is capable to contain charge). cheers!!

Why do inductors resists a change in current?
An inductor charges and discharges. When an alternating current come up, the positive signal of the current quickly charges up the inductor. when the negative signal part of the same cycle comes up the inductor develops a potential to opposes it. this is because any charge developed opposes if there is a change or break or whatever for that matter, in supply. so, the negative signal which is basically a change in signal when approaches the inductor the charge developed across it opposes it and as the charge developed thanks to the positive part of the signal is used up to oppose the negative part of the same signal, basically the charge is zero. thus an alternating current or high frequency current for that matter, does not pass through an inductor.CommentI think the above answer has confused inductance for capacitance! No charges are involved with inductors.Whenever current changes in an inductive circuit, a voltage is induced into that circuit. The magnitude of the induced voltage depends on the rate of change of current. The direction of the induced voltage is such that it opposes the change in current -for example, if the current is reducing in value, then the induced voltage will try to maintain that current.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
Does an inductor work in both ac and dc?
Depends on what you mean by work. It still opposes changes in the current flow through it, that doesn't change. But as DC has no phase, it produces no phase shifts as it does in AC.
