Introduction of electric current.

HELLO DEAR HERE ARE SOME TOPIC ABOUT ELECTRIC CURRENT..............................

  ELECTRIC CURRENT


Electrical current is a measure of the amount of electrical charge transferred per unit of time.

It represents the flow of electrons through a conductive material, such as a metal wire. 

UNIT OF ELECTRIC CURRENT

The electric current is measured in=AMPERE
                                    
SYMBLE OF ELECTRIC CURRENT


The conventional symbol for current is I, which originates from the French phrase intensité de courant, meaning current intensity.

 Current intensity is often referred to simply as current.
The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named. 

TYPE OF CURRENT
The electric cuurent is of two types=======
[a]=Direct current[D.C.current]
[b]=Alternating current[A.C.current]

DIRECT CURRENT
Direct current (DC) is the unidirectional flow of electric charge. 

The electric charge flows in a constant direction, distinguishing it from alternating current (AC). 

A term formerly used for direct current was galvanic current.
Direct current is produced by sources such as batteries, thermocouples, solar cells

ALTERNATING CURRENT

In alternating current (AC, also ac), the movement of electric charge periodically reverses direction. 

In direct current, the flow of electric charge is only in one direction.
AC is the form of electric power delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave. 

Certain applications use different waveforms, such as triangular or square waves.
FORMULA OF ELECTRIC CURRENT
    The magnitude of the flow of current at any section of the conductor is defined as the rate of flow of electrons.
Mathematically, this can be represented as:
                              [ I = Qt
Where,
IElectric current
QElectric Charge
TTime
        SOME NUMERICAL OF ELECTRIC CURRENT AND CHARGE

[1]=Find amount of cuurent produce in a conductor of charge 8 coloumb in 3 seconds.
[2]=Find amount of current produces by each cloumb of charge in 1 second.
[3]=find number of electron present when 4 ampere of current is produced in 7 seconds.
[4]=what does time take to produce 8 ampere of current in 4 electrons..
