Electricity in transit Flashcards
What does the movement of electric energy depend on?
The movement of electrical energy depends on the movement of electrical charge
What is this pathway of electricity called?
The pathway is called anelectric circuit
What is the property of electrons that makes electricity work?
Electrons are able to move from one atom to another
What creates electricity?
It is this movement of electric charge (electrons) that creates electrical energy
What is the movement of charge or electrons called?
The movement of charge, or electrons, is called the electrical current
What is electrical conductivity?
Electrical conductivity is the ability of electrons to move in a substance
What are substances that allow electrons to move easily called?
Substances that allow electrons to move easily are called conductors
What sort of atoms do conductors contain?
Conductors contain atoms in which electrons (-) can move freely
Give a few examples of conductors
steel
brass
bronze
mercury
graphite
dirty water
What are insulators?
Substances in which it is difficult for electrons to move are insulators
What sort of atoms do insulators contain?
Insulators contain atoms that hold on to their electrons tightly
Give examples of insulators
glass
rubber
oil
asphalt
fiberglass
porcelain
ceramic
