10.2 Static electricity Flashcards
What are atoms made up of
Sub-atomic particles
Types of subatomic particles
Protons
Electrons
Neutrons
Protons
Type of subatmoic particle that is postiviely charged
Electrons
Type of subatomic particle that is negatively charged
Neutrons
Type of subatomic particle that has no charge
What kind of energy does an atom have
nuclear energy
What is the number of protons equivalent to
Number of electrons
Electricity
Electricity is a result of interaction
between charges
How is electricity produced
Electricity is produced when electrons and protons are separated and
re-united.
How do electrons transfer from one object to another
2 objects are rubbed together
Electrical conductors
materials that allow for electrons to flow
easily and have low resistance
Electrical Insulators:
Materials such as rubber that don’t allow electrons to flow, can leak charge slightly and have high resistance.
How can charge move between insulators
when two insulators are rubbed together
Semi-conductors
are materials that are insulators in their pure form, but become
conductors when combined with small amounts of another substance eg. silicon
Electrostatic charge
Electrostatic charge is the build up of charge on an uncharged
object or surface.
