Static Electricity Flashcards
Electricity
The flow of electrons
Static electricity
A stationary electrical charge that has been built up on the surface of a material
Negatively changers objects have…
Gained electrons
Positively charged objects have…
Lost electrons
Insulator
Materials that do not allow electrons to flow through it easily
What can insulators be charged with
They can easily be charged by friction as the extra electrons gained cannot easily escape
Conductors
Materials that allow the electrons to flow through it easily
Charged objects…
Repel
Oppositely charged objects…
Attract
Earthing
Connecting a charged object to the earth by using a conductor so that most of the charge which was on the object flows into the earth
Useful effects of static electricity
Removing door from chimneys
Spray painting
Bad effects of static electricity
Television screen attracting dust
Lighting
What does a positively charged ion have more of then something else
More protons then electrons
What does a negatively charged ion have more of then something else
More electrons than protons
What is ohms law directly proportional to?
The current
