Uses and Dangers of
Static Electricity
- Good uses
- Paint sprayers use electrostatic
charges to get an even coat
- Bikes and cars are painted in this way
- Method:
- 1. The spray gun is
charged, this also
includes the small drops
of paint
- 2. The paint drops repel
the others; this makes them
spread out leaving the bike
with an even coat
- 3. The object to be painted will be given an opposite
charge to the electrostatic gun, this attracts the
negative paint in the gun to give a fine spray of paint
- You can use electrostatic
sprayers in other ways; such
as insecticide sprayers

- 1. The spray gun is
charged, this also
includes the small drops
of paint
- Using this method, hardly any paint is wasted in the
process which makes it cheaper and in some ways
quicker; mainly because you don't have to spend
along time trying to get an even coat when the
positive and negative charges are doing it for you
- Bikes and cars are painted in this way
- Paint sprayers use electrostatic
charges to get an even coat
- Disadvantages to Electrostatic charges:
- When filling up the tank of a
car with fuel, it can easily
lead to a spark which might
cause an explosion. This
could occur in fumed places
such as when filling a car
with petrol in a petrol station
- This happens
when fuel
flows out of a
pipe and static
charge builds
up
- However, if you
earth charged
objects this would
not happen
- However, if you

- When filling up the tank of a

- Earthed objects can stop
electrostatic charge from
building up
- This can prevent dangerous
sparks from occurring, you do this
by connecting a charged object to
the ground using a conductor
- You could use a copper wire for instance
- This provides an easy route for the
static charges to travel into the
ground; which means no charge can
build up and give you a shock
- The electrons flow down the conductor to the ground if the
charge is negative, and up if the charge is negative. Either
way, the object will become earthed with a neutral charge
- Earthing objects such
as an aircraft are very
important to prevent
charge building up in
one place so there
aren't any sparks
which could lead to an
explosion
