Electricity is a flow of electrons from an area of high electron excess to low electron content. It is formed when energy causes electrons to dislodge from atoms, creating positive and negative ions. There are two types of electricity: static electricity which occurs when objects are rubbed together and electrons move between their surfaces, and dynamic electricity which is moving electrons that create an electric current. Sources of electricity include friction, chemical reactions like those in batteries, and other processes that cause the movement or imbalance of electrons in materials.

1. Electricity
- Comes from the ancient Greek word for amber -
elektron.
- Is a flow of electrons from an area high in
electron excess to one lower electron content.

2. BASIC CONCEPTS IN ELECTRICITY
How electricity is formed?
When an element is divided continuously, the division will
arrive to the smallest particles where it can no longer divide.
This smallest particle of an element is called the atom.

3. A neutral atom consists of an equal number of protons and
electrons.

4.  When energies such as heat, light, chemical, friction, pressure and magnetic action is subjected into an
element, the electrons are dislodge from their orbit.

5.  A positive ion will attract a
negative ion. This ionic
condition gives rise to static
electricity.

6. KINDS OF ELECTRICITY
A. Static Electricity
-When two objects rubbed together,
electrons are remove from surface atom,
from one material to the other.
A. Dynamic Electricity
-this refers to electrons in motion. Moving
electrons constitute electric current

7. Sources of Electricity
 Friction
 Rubbing the flexi glass with feather, will cause its electrons to escape and
leave the flexi glass positively charged. When the flexi glass is placed near
the paper, it will attract the electrons of the atoms of the paper.

8. Chemical Reaction
 dry cell
 The chemical reacting with metal a causes electrons from the atoms of
metal A to escape. These electrons are caught by the atoms of metal B.
Since A has lost its electrons, it becomes positively charged. Metal B
which gains electrons becomes negatively charged. The formation of
positive and negative charge at each end of a dry cell is also another
form of static electricity.
