Electrical System are concerned with the behavior of three fundamental quantities like charge, current and voltage.
Charge:
The charge carried by electrons of an atoms is called electricity.And it is represented by Qunit of charge is coulomb 'c' .
Current:
Continuous flow of electrons in a conductor in a particular direction is called electric current. or
Rate of flow charge in a conductor in a particular direction is called current (I)
It is represented by I.
SI unit of current is Ampere.
Voltage:
It is the measure of electrical pressure between two points of a electrical circuit.
When a current exists electrical energy is usually being transmitted from one part to another.
Electrical system consists of two categories:
1.power system
2.communication system
