What does a inductor do in a circuit?
DC current has no effect on the inductor(can be considered as a short circuit) as the current does not change in a DC supply voltage this one just produces a magnetic field which remains constant , as the magnetic field is not varying no emf is induced in the circuit , so literally it has no effect on the circuit when the supply is of DC voltage.when an alternating current is set up in a circuit , the Alternating current brings a magnetic field in the inductor which is variable (since the current is varying...) this variable magnetic field induces an emf in the circuit (back emf) which opposes the cause that is producing the change (lenz's law)explanation consider a circuit with an inductor connected to an AC voltageduring the positive half cycle when the voltage increases the current also increases in the circuit [take the current direction as clockwise] this causes a variable increasing magnetic field in the inductor , this magnetic field in turn induces current in the circuit which is opposing the increase in the current flow from the original source, the inverse happen during the decreasing half of the half of the positive cycle , here the induced current adds up with the decreasing current opposing the cause that produced this back current (cause :- decrease in current changes the magnetic field so the induced current is produced ..... it is opposing the change because :- the induced current either decreases the increasing current or increases the decreasing current )
What is the difference between coil inductor solenoid?
Physicall no difference.But inductor uses ac and solinoid uses dc.
Why is the resistance of an inductor low?
Because the whole point of an inductor is to store energy and then give it all back, without dissipating any of it.
Which type of friction opposes the motion?
Static friction is the type of friction that opposes the motion.
Is the upward force that opposes the force of gravity?
Lift is the upward force that opposes the force of gravity.
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 there are only RC filters and not RLC filters used with IC.why inductor is not used?
The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.
What does a inductor do when connected across ac supply?
opposes changes in current
Why an inductor opposes the flow of alternating current?
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.
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.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
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.

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.
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.
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!!

Inductors and its types?
INDUCTORS are a type of passive electrical devices that are used to store energy from magnetic fields and release it when needed.The electronic component(mostly a coil) which opposes the changes in current in circuit is called an inductor . The ablitity to oppose the change of current flowing through is it is called inductance of the coil / inductor .The inductance of an inductor may also be defined as ablity to produce induced voltage when current varies through it .
