3. • Electricity is an
important part of
our life. Since
electricity is a form
of energy, it is
capable of doing
work.
4. • Static Electricity-
Is the accumulation of
electric charges on an
object.
Electrically charged
objects obey this rule-
opposite charges
attract, like charges
repel.
7. • Conductors-
Materials that allow electrons
to move easily through it.
Current moves through
conductors because electrons can
move easily through materials
that do not hold their electrons
tightly.
Copper, aluminum, and silver
are good conductors.
8. • Insulators-
Materials that do not
allow electrons to move
through it easily.
Plastic and rubber are
good insulators.
9. • Electromagnetic Induction-
Is the process in which
the motion of wire through a
magnetic field produces a
current.
Most of the electrical
energy converted to useful
electricity by electromagnet
induction.
11. ENERGY SOURCES MAY BE
CLASSIFIED……….
• CONVENTIONAL SOURCES
ARE THE COMMONLY
USED SOURCES OF ENERGY
• NONCONVENTIONAL
SOURCES
ARE THE ALTERNATIVE
SOURCES OF ENERGY
