Static electricity Flashcards
Which force generates static electricity?
Friction
Which particles are transferred between surfaces?
Electrons
What charge will an object have if it gains electrons?
Negative
What charge will an object have if it loses electrons?
Positive
In which group of materials does static electricity occur?
Insulators
State the wire that disperses the static charge safely
Earthing wire
How do objects become positively charged?
By losing electrons
How do objects become negatively charged?
By gaining electrons
What will happen if two objects with similar charges are
brought together?
Repel
What will happen if two objects with different charges are
brought together?
Attract
How can you tell if an object is charged?
Repels another object
What happens when negative charge builds up in an
insulator?
A spark
State two uses for static electricity
Photocopiers and spray painting cars

charged sphere with a positive charge?
