What is an atom?
It is a buildup of electric charge.
What is static electricity?
These are objects that electricity cannot flow through steadily.
What are insulators?
What is the best material to make a circuit?
Metal such as copper
These are protons, neutrons and electrons.
What are the three charges in an atom?

Earth
The movement of electrons is called as _________?
What is electricity?
These are objects electricity can easily flow through.
What are conductors?
You need this to make a full circuit
power source
What happens to like charges?
They repel each other.
What charges are clustered in the middle of the atom?
Positive and Neutral charges
Connecting an object to Earth with a conducting wire to prevent the buildup of static electricity.
What is grounding?
It protects homes from high currents.
Circuit breakers / fuse/ GFCI
A circuit that is incomplete
What is an open circuit?
When equal charges comes close to each other____________
It becomes neutral.
The positively charged particles of the atom are called as _________
protons
A flow of electricity through a conductor.
What is electric current?
A path with little or no resistance that connects the two ends of an electrical source is a (n)
Short Circuit
A unit to measure electrical energy.
What is Volt?
___________ occurs when objects with opposite charges stick together.
Static Cling
Why do only electrons move from atom to atom?
Electrons are on the outside and easier to break off than the protons and the neutrons which are in the middle of the atom.
An object in an electric circuit that resists the flow of electrons.
