Transcript of Uses and Dangers of Static Electricity

Uses and Dangers
of
Static Electricity Static electricity can be used for many
purposes. Many car manufacturers use
static electric to paint their vehicles
before putting them on the market. They do this by charging the paint and
the car with opposite charges (positive
and negative), so that, when they meet,
the paint is drawn to the car and 'sticks'
to it. Electrostatic Car Painting Dust Removal Using static electricity, some
air purifiers can alter the charge
in dust particles, thereby drawing
them towards a plate or filter with
the opposite charge, removing the
dust from the air. Photocopying It is also possible to, through
a very similar process, draw
ink towards a page in a
photocopier. This is a method
used by many machines in
lots of different companies. However, static electricity can
also be very dangerous, often
resulting in serious injuries
or death. Dangers of Static Electricity Car Pumps Through the motion of a body
rubbing up against a car seat,
static electricity can be produced.
This electricity can build up without
having any place to go. When the pump
comes in contact with the vehicle, the
static electricity can transfer to the
nozzle. This can create a spark which, if
it touches the gas supply, will cause an
explosion. Explosions tend to kill people,
thus being labelled a danger. Electric Shock In many circumstances, static
electricity can build up, such
as in a wall socket. Coming in
contact with a metal object
that contains a build up of
static electricity can cause an
electric shock. High voltage
electric shocks can cause a
person to become paralyzed,
develop paranoia or even die,
again, giving a reason for this
to be labeled a danger. Thank you for
