Come, friends today, we will know what is this Coil?
How does coil work?
Base or What is a core?
And what is the identity of Coil?
So let's see below  What is a coil?

 Have you become upset then this is the solution

Coil  : -

If the coil is in any circuit, it is represented by (L). And coil is an important component of electronics circuit.  It's all kinds You can easily see these components in an electronics device.  Of coils Use filters, boost signal, and more Is brought into.

What are coil  : - 

A coil is actually a wire.  Which can be of any conductive material like: Copper, aluminum, iron etc.  When you put the insulating material around this wire goes.  Which is called insulation.  Whereby the wires are called insulated wires and If the base is wrapped round or without the base, then the parts made of this type It is said.  The insulation is applied so that the wire does not shorten when it is wrapped.  Current There is no obstruction in the middle, which can be obtained from the other end only through the wire end.

How does coil work  : -

When AC (variable electric current) is given to any coil, given in the coil Voltages of polarity are produced in contrast to the supply.  The supply given in this voltage coil
Opposes  If you wrap the wire without any core or conductor.  It is called the Air Corps.

What is the base or core  : -

When a coil is made, it is wrapped on a conductive metal then it Its core is called.  Ferrite when wrapped on the basis of iron or ferrite The core or iron core is called.

 In simple language, when given AC volts in insulated wire, the magnetic field around the wire In which the two poles of the magnet become North pole and South pole.  When wire If we wrap it up, these polles oppose each other.  This would be the quality of the coil Due to which opposing volts are generated.  This is called Inductance.

The inductance of the coil is affected according to the thickness, length and area of ​​the wire.  more Wrapping, thickness and area increase the inductance of the nearest coil.

The inductance of the coil will be higher if the wrap of the coil is higher, similarly if the wrap is less If it is, the inductance will also be less.  It means to say that as the inductance increases The coil will pass at low frequencies.  If the inductance is low, the coil passes to high frequency Will do.

How to check  : -

If we check the coil from anlog multimeter, then the needle does not move at all. In this case the coil is defective.  If the coil is correct, the needle of the multimeter moves from its first end Go to the end.
