Download What is current electricity

What is current electricity?
• Current electricity is power or a charge
that flows in and out through a medium
such as electrical wires. It can be stopped
or started by opening or closing the wire
connection as in turning a light switch from
off to on.
How does current electricity
work?
when electrons move from one atom to
another, this creates an unbalance or
flow, which is called an electric current.
Why do we need it?
It powers our computers, lights,
appliances, and much more.
What is static electricity?
• It is the build up of an electric charge on
an object's surface.
How does static electricity work?
• Static electricity works by
transporting stored energy in
stationary objects to moving
ones. everything has stored
energy. For instance try rubbing
a balloon on your hair and then
sticking it to a wall.
Why is it important to understand
static electricity
• We need it because without it we wouldn’t
be able to move static electricity

Static electricity is usually a 'high voltage' but low power form of electricity.
Lightning is static electricity, and it can damage buildings and harm people.
Dangers of Electricity include a variety of hazards that include Electric
Shock, Psychological Damage, Physical Burns, Neurological Damage and
Ventricular fibrillation resulting in death.
Any form of energy, when not properly controlled or harnessed, can result in
serious danger to those who use it. The risks inherent with electric power
can generally be divided into two categories: direct and indirect. The direct
danger is the damage that the power itself can do to the human body, such
as stoppage of breathing or regular heartbeats, or burns. The indirect
dangers of electricity include the damages that can result to the human
body as a result of something caused by electric shock, such as a fall, an
explosion, or a fire.
Electricity at any voltage can be dangerous and should always be
approached with caution. An electric shock can occur upon contact of a
human or animal body with any source of voltage high enough to cause
sufficient current flow through the muscles or nerves. The minimum current
a human can feel is thought to be about 1 milliampere (mA). As little as 80
milliampere, can seize the heart m
safety procedures for dealing with
current and static electricity
• Current electricity can kill you if it is not
contained and kill seriously burn you
• Any kind of electricity can kill u or at least
put you in the hospital
