Static Electricity-Your Dryer's Best Friend
Static Electricity is a collection of electrical
energy (charge) in one spot. Have you ever received a little
shock? If you put on your shoes and drag your feet across the
carpet on a very dry day, then touch the doorknob, you might
see, hear and feel the discharge of static electricity. You
see the electricity as a tiny flash of light, you hear the
sound of crackling, and you feel a slight shock. Even more
powerful, a lightning bolt is an example of the discharge,
or movement, of static electricity.
You can collect static electricity in one spot by moving electrons
around. Have you ever rubbed a balloon on your head and then
your hair stuck to the balloon? Have you rubbed a plastic comb
with a wool sweater and then picked up puffed rice or tissue
paper with the comb? Have you ever taken the laundry out of
the dryer and your socks were stuck to your shirts and they
crackled when you pulled them away?
Objects charged with static electricity can attract or repel
other objects. Attract means to draw together. Repel means
to push apart. Opposite charges attract and like charges repel.
When you rubbed the balloon on your head some of the electrons
moved around and your hair became positively charged and the
balloon became negatively charged. Those were opposite charges
so the balloon and your hair attracted each other. The comb
had a different charge than the puffed rice so the comb and
the puffed rice attracted each other. I’ll bet you never
knew that your shirts and your socks were moving electrons
around in the dryer till they became attracted to each other!
Static electricity is
a form of energy. Static electricity is
a build up of electrical charge in one spot, until it moves
or is discharged. Sometimes, you can see, hear and feel static
electricity when it is discharged. Lightning
is a powerful form of static electricity.
