Electricity3
electron
neutron
proton
Electricity is generated from the motion of tiny charged atomic particles called electrons and protons.
Electricity is the flow of electrical power or charge.
>> found out that amber when rubbed with fur can attract light materials such as straws and feathers.
>> described the electrification of many substances and coined the term “electricity” from the Greek word for “amber”.
>> Father of Modern Electricity
defined as the study of electricity at rest.
the fundamental entity in
electrostatics.
It can be transferred from one body to another by friction or rubbing, conduction and induction. >> is the transfer of
>> is the movement of electrons to one part of an object by the electric field of another object.
>> is the transfer of electrons from a charged object to another object by direct contact.
1. Positive charge (+) –
“a deficiency of electrons”.
2. Negative charge (-) –
“ a surplus of electrons”.
The field lines are originated from the positive charge.
The field lines end up at the negative charge.

Negative charge electric field
A positive charge exerts out and a negative charge exerts in equally to all directions; it is

>> materials whose electric charges are free to move within.
Ex. Copper, aluminum, silver, iron, carbon, water
>> materials whose electric charges are not free to move within.
Ex. Glass, plastic, rubber, silk
>> materials that allow only some charges to flow through.
Ex. Silicon, Germanium
>> materials which totally allow current to pass through without any resistance.
>> states that like charges repel and unlike charges attract.
>> states that the force of attraction or repulsion between two small charged bodies is directly proportional to the product of the two charges and inversely proportional to the square of
