Static Electricity 2
- Static electricity can cause little sparks or shocks
- Clothing crackles: When synthetic clothes
are dragged over things like in the dryer or
your head, electrons get scraped off leaving a
static charge on both objects. This leads to an
attraction and little sparks as charges
rearrange themselves
- Car shocks: Static charge can build up between your
clothes and a synthetic char seat. The friction causes
electrons to be scraped off, and when you get out of the car
and touch the metal door; charge flows which gives you a
'buzz'. To prevent this from happening, some cars have
conducting strips which hang down the side of the car and
discharges you safely to earth
- Shocks from Door Handles: If you walk
on a nylon carpet with shoes which have
insulating soles; there will be a transfer of
electrons from the carpet to you and
charge will build up in your body. If you
touch the metal door handle to go into the
next room; the charge will flow from you
to the conductor, this will give you a little
shock.
- An example of this would be a balloon sticking to the wall; if you rub a
balloon on your hair it causes electrons to be transferred to the balloon,
this leaves it with a negative charge. The negative charge in the balloon
attracts to the wall if you hold it up against it and sticks. The wall isn't
charged but the negative charges in the balloon repel the negative
charges at the surface of the wall. This then leaves the positive charges
in the wall to attract the negative charges in the balloon. Opposite
charges attract one another letting the balloon stick to the wall.
- Some electrically
charged objects can
attract other objects
- Some electrically
charged objects can
attract other objects
- Charged combs can pick
up tiny pieces of paper,
when you run a comb
through your hair it gains a
negative build up of
charge, this negative
charge can pick up tiny
pieces of paper (with no
charge)
- Charged objects attracting uncharged objects
is called induction. The charges in the charged
object force a charge in the uncharged object
which causes it to move or stick
- An example of this would be a balloon sticking to the wall; if you rub a balloon on your hair it causes

- Charged objects attracting uncharged objects

- Lightning is also the
result of static charge; in
storm clouds rain drops
and ice bump together;
this knocks off electrons
leaving the top of the
cloud positively charged
and the lower negatively
charged. This creates a
huge voltage and a big
spark of lightning
