INDUCTOR , CAPACITOR & CONDUCTOR
Conductor
What is the Conductor :question:
:pencil2:Conductors are the materials or substances which allow electricity to flow through them.
:pencil2: They are able to conduct electricity because they allow electrons to flow inside them very easily.
:pencil2: Conductors have this property of allowing the transition of heat or light from one source to another.
:pencil2: Conductors have free electrons on its surface which allows current to pass through. This is the reason why conductors are able to conduct electricity.
Example of conductors :
:one: Silver is the best conductor of electricity. However, it is costly and so, we don’t use silver in industries and transmission of electricity.
:two: Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity. We use them mostly in electric circuits and systems in the form of wires.

Inductor
What is Inductor :question:
:pencil2: an electric component that has characteristic against the change of current.
:pencil2: Also called as chop or coil.
:pencil2: Designed to produce a much stronger magnetic field than one that would produce by a simple coil.
:pencil2: An inductor is usually constructed as a coil of conducting material, typically
copper wire, wrapped around a core either of air or ferrous material.
:pencil2: Core materials with higher permeability than air confine the magnetic field closely to the inductor, thereby increasing the inductance.
:pencil2: Some inductors have an adjustable core, which enables changing of the inductance.
:star:Unit
Henry(H)
1 Henry = total inductance of winding if the current in the rate of 1 ampere per second and produced induced voltage for 1 volt.
:star:Symbol
L
Inductance ʹ
:pencil2:the property of an electric circuit by which an electromotive force is
induced in it as the result of changing magnetic flux.

Capacitor
What is Capacitor :question:
:pencil2: an electrical device that is used to store electrical energy.
:pencil2: A capacitor has capacitance of one Farad when current charging of one Ampere
flows in one
:pencil2: In its most elementary state a capacitor consists of two metal plates separated by a certain distance d, in between the plates lies a dielectric material with dielectric constant сɸoɸ͕ where ɸo is the dielectric of air.
:pencil2: The dielectric material allows for charge to accumulate between the capacitor plates.
Air ;actually vacuumͿ has the lowest dielectric value of ɸo = 8.854 x 10-12 Farads/meter.
:pencil2: the capacitance is related to the dielectric of the material in between the plates, the square area of a plate and the distance between the plates
by the formula: C = (E0 X EA ) / D
:pencil2: the larger the area of the plate the more charge can be accumulated and hence
the larger the capacitance.
Capacitance
defined to be the amount of charge Q stored in between the two
plates for a potential difference or voltage V existing across the plates
