2. CAN YOU IMAGINE
YOUR LIFE
WITHOUT ELECTRICITY?
in ancient times fire was an source of light, heat and cooking by
rubbing two stones.
when two stones are rubbed together, there is friction and we all
know about the heating effect of friction, so due to the heat
produced due to friction, sparks are produced to cause fire.
so fire is useable as a electricity source.
3. since that time, the development of
technical ideas allowed to reach a new level
of human life.
4. HOW ELECTRICITY IS PRODUCED.
electricity is the flow of electrons from one place to
another. electrons are negatively charged
subatomic particles. if one of these electrons is
freed from an atom and forced to move, electricity
is produced.
5. There are many ways to produced electricity and
people can use in our homes.
HYDRA POWER PLANT.
WIND TURBINE.
SOLAR PLANT.
7. HOW HYDRA TURBINE
WORKS.?
The most common type of
hydroelectric power plant uses
a dam on a river to store water
in a reservoir. Water released
from the reservoir flows through
a turbine, spinning it, which in
turn activates a generator to
produce electricity.
This is called hydroelectric
power or hydropower
you can see Reserve water
flows and turbine move to
generate electricity.
8. WIND POWER PLANT.
Wind turbines operate on a simple principle.
The energy in the wind turns two or three
propeller-like blades around a rotor. The rotor
is connected to the main shaft, which spins
a generator to create electricity
• it can covert kinetic energy from the wind
into electrical power.
• Bigger wind turbines can be used to create
large amounts of electricity that can be sold
to electrical companies.
9. SOLAR POWER PLANT.
Solar power is the conversion of
sunlight into electricity either
directly using photovoltaics
Solar power systems use lenses or
mirrors to focus a large area of sunlight
into a small beam.
Photovoltaics convert light into
electric current using the
photovoltaic effect.
It’s can generate D.C current
They can store electricity in battery and
you can use in our home.
10. That’s another solar power plant to
generate large amount of electricity.
Solar reflectors reflects light on tower.
Water is heated up and steam produced
to move the turbine generator and large
amount of electricity is produced
