2 types of electric charges
positive + negative charge
1 of 15
An example of an insulator
wood and polyetehne
2 of 15
How can a charged object be dishcharged?
have the excess charge removed / earthing it.
3 of 15
What electric charge do electrons have?
Negative
4 of 15
How to generate static electricity?
rubbing a balloon against your hair
5 of 15
One problem with static electricity
dirt and dust to be attracted to insulating materials. e.g. tv screens
6 of 15
What will two of the same charges do to each other?
Repel
7 of 15
What will two different charges do to each other?
Attract
8 of 15
How does electric or static charge build up?
when electrons are rubbed off one material onto another
9 of 15
The material that receives electrons becomes what electric charge and why?
negatively charged because of the excess of electrons
10 of 15
The material giving up electrons will become what electric charge and why?
positive charge because there is a loss of electrons
11 of 15
How does an individual reduce the chance off getting an electrical shock?
By making sure the appliances are correctly earthed
12 of 15
Atom and molcules that have becomed charged are called?
Ions
13 of 15
The names of uses of electrostatics
smoke precipitators, defibrillators and spray painting
14 of 15
what is the job of the defibrillators?
Two paddles are charged and put in good electrical contact with the patients chest, the charge is then passed through the patient to make the heart contract
