we use the inductor because it helps the circuit to have an appropriate amount of current, so that the circuit in the appliance will say longer.

How do you increase the inductance in a inductor?
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
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.
In which place an inductor store energy in it?
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.
What is the Value of currie temperature?
Each inductor has its own currie temperature. You have to check the datasheet for the specific inductor in use.
What devices do you use to store electricity?
capacitor inductor battery
Why we use the inductor?
To answer these questions I will tell you which devices or equipments are inductive.These include:TransformersHair clipers,hair blowers,motorsYou hopefully know what those devices or equipments are used for,hence why we use inductors.
Why is an inductor used for?

How do you increase the inductance in a inductor?
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
Can you use inductor in low pass filter?
Type your answer here..yes.
How to calculate the inductance of a home made inductor?
To calculate the inductance of a home made inductor simply take the number of turns,the magnetic flux linkage and the current and use the inductance formula.
How can you determine resistance of inductor in single phase with DC source?
Your question is confusing -is the inductor supplied with a.c. or d.c.?In either case, you can determine the inductance of an inductor by disconnecting it, and measuring its resistance with an ohmmeter. If you want a really accurate value of resistance, you could use a Wheatstone Bridge, instead.
Can we use a DC source with an inductor?
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
What is the use of resistance in a LC circuit?
every inductor has some resistance. In circuit diagram, ideal inductor is shown in series with a resistor(value being equal to coil's resistance) to make analysis easy.
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
Why don't us use inductor and capacitor in attenuator design?
Unwanted phase shift, probably.
