Introduction:
Electricity is a form of energy. I mean it is the flow of electrical power or charge.
It is called electricity.
OR
Electricity is a set of physical phenomena attendant on showing and motion and matter that has a the belonging of electric charge.
The electricity includes these things (lightning, electrical heating , Dc Moter, AC motor, electric discharges, electrical tools, electronics devices, static electricity, electric heating,and many others.
As you know, electricity life is settled by electrons (charges).
· The appearance of an electric charge, which can be each of two.
positive or negative, generate an electric field. The change of electric charge is an electric current and makes a magnetic field.
coulomb's law:
The force of attraction or reputation between two electric charges is direct proportions to the product of (charges ) and inversly propertional to the sqaure of the distance between them.
Electric charges:
As we know, electric charges are property of the subatomic particles. That is to understand a force when placed in electric and magnetic fields.
Resistance:
It is the opposition to electrical currents. It is called resistance and it is good.
example (Rubber).
The S.I unit = (OHM).
Conductor:
The flow of electric current is called conductor and a good example
(Electric wire)
The S.I unit = SIEMENS per meter (s/m)
Conductivity:
It is the measure of electrical current. I mean how much current in any material is called conductivity.
The S.i unit = sam like conductor
Insulators:
those things which can not pass the electric current, is called insulators.
The S.I unit = Ohm.
