3. *Electricity is a form of energy that is all around
us.
*Electricity is the set of physical phenomena
associated with the presence and motion of
matter that has a property of electric charge.
*A form of energy that can be produced in several
ways and that provides power to devices that
create light, heat, etc.
4. Electrical Energy
* It is the power an atom's charged particles have to cause
an action or move an object.
*The movement of electrons from one atom to another is
what results in electrical energy.
*Electrical energy is used as a substitute for fuel and
replaces it in many industrial applications. There are
several sources by which electricity can be generated,
6. to look at
what makes up electricity. To begin, all things in nature are made up of
matter.
Matter is a substance made up of various types of particles
that occupies physical space and has inertia. According to
the principles of modern physics, the various types of
particles each have a specific mass and size.
There are many possible definitions of matter. In
science, matter is the term for any type of material.
Gold and iridium are matter, as are peanuts, people, and
postage stamps. Smoke, smog, and laughing gas are
matter. Energy, light, and sound, however, are not matter;
ideas and emotions are also not matter.
Matter cannot be described by colour, taste, and
hardness. These
are observable characteristics that truly do not
define what the substance
is made of.
7. To understand this further, matter can be
broken down into smaller parts
called molecules. Molecules are so small
that they cannot be seen by the
naked eye. Molecules are made up of even
smaller particles called atoms.
These atoms are so small that a piece of
copper the size of the head of a
pin would contain millions of atoms.
8. Atoms can then be broken down
even further into sub-atomic particles. These
smaller sub-atomic parts of
an atom are known as protons, electrons, and
neutrons. It is one of these
particles that provides the energy to power
electronic and electrical
devices.
When all atoms in a substance are alike, the
substance is called an
element.
9. 3
There are just over 100 elements in total. Each of these elements
is then broken down into its own physical, chemical, and electrical
properties. They all have very unique qualities. Some examples of
elements that make electricity and electronics possible are copper,
aluminum, carbon, gallium, germanium, neon, oxygen, silicon, gold, and
silver.
