Static electricity occurs when there is an imbalance between positive and negative charges within or between objects. This can cause effects like receiving a shock from touching something after walking across a carpet. It is also responsible for phenomena like hair standing on end after removing a hat. Static electricity is the result of an imbalance of electric charges, which can build up until being discharged through a circuit or other object. Lightning is also a type of static electricity, where positive and negative charges separate within a thundercloud, building up a difference until discharging as lightning.

1. Static Electricity TOPIC : MACHINE : MAGNET
AND ELECTRICS

2. What is electrity??
Electricity is all around us--powering
technology like our cell phones, computers,
lights, soldering irons, and air conditioners.
It's tough to escape it in our modern world.
Even when you try to escape electricity, it's
still at work throughout nature, from the
lightning in a thunderstorm to the synapses
inside our body.
But what exactly is electricity? This is a very
complicated question, and as you dig
deeper and ask more questions, there really
is not a definitive answer, only abstract
representations of how electricity interacts
with our surroundings

3. Electricity is
“Electricity is the flow of electrical
power or charge. It is a secondary
energy source which means that we
get it from the conversion of other
sources of energy, like coal, natural
gas, oil, nuclear power and other
natural sources, which are called
primary sources. The energy sources
we use to make electricity can be
renewable or non-renewable, but
electricity itself is neither renewable
or non-renewable”.

4. But, How about static electricity??
► Have you ever walked across the
room to pet your dog, but got a shock
instead? Perhaps you took your hat off
on a dry winter’s day and had a “hair
raising” experience! Or, maybe you
have made a balloon stick on the wall
after rubbing it against your clothes?
► Why do these things happen? Is it
magic? No, it’s not magic; it’s static
electricity!

5. To know more about static electricity
in our daily life.

► Or you can try to conduct experiment
at home by using :
► Comb and piece of paper, or use
baloon by rubbing it into your hair.

6. the components of an atom
► All physical objects are made up of
atoms. Inside an atom are protons,
electrons and neutrons. The protons are
positively charged, the electrons are
negatively charged, and the neutrons
are neutral.
► Therefore, all things are made up of
charges. Opposite charges attract each
other (negative to positive). Like charges
repel each other (positive to positive or
negative to negative). Most of the time
positive and negative charges are
balanced in an object, which makes
that object neutral.

7. “hair raising” experience
► what about that “hair raising”
experience? As you remove your hat,
electrons are transferred from hat to
hair, creating that interesting hairdo!
Remember, objects with the same
charge repel each other. Because
they have the same charge, your hair
will stand on end. Your hairs are simply
trying to get as far away from each
other as possible!
► Static electricity is the result of an
imbalance between negative and
positive charges in an object. These
charges can build up on the surface
of an object until they find a way to
be released or discharged. One way
to discharge them is through a circuit.

8. How was lightning happens?
► Lightning is an electrical discharge
caused by imbalances between storm
clouds and the ground, or within the
clouds themselves. Most lightning
occurs within the clouds.

9. How was lightning happens?
► Lightning is an electric current. Within
a thundercloud way up in the sky,
many small bits of ice (frozen
raindrops) bump into each other as
they move around in the air. All of
those collisions create an electric
charge. After a while, the whole cloud
fills up with electrical charges. The
positive charges or protons form at the
top of the cloud and the negative
charges or electrons form at the
bottom of the cloud.
► Since opposites attract, that causes a
positive charge to build up on the
ground beneath the cloud. The
grounds electrical charge
concentrates around anything that
sticks up, such as mountains, people,
or single trees. The charge coming up
from these points eventually connects
with a charge reaching down from
the clouds and - zap - lightning strikes!
