100
What what kind of charge does a proton have?
A positive charge.
200
What kind of charge does an electron have?
A negative charge.
200
What kind of charge does a neutron have?
A neutral charge.
200
What two parts attract each other?
Positive and negative.
200
What is a charge?
A measure of the extra positive or negative partices that an object has.
200
What is static electricity?
A charge that stays on an object.
300
What do unlike charges do?
Attract each other.
300
What do like charges do?

300

What is a circuit?

A current that moves along a wire or path in a single direction

300

What is a series circuit?

A circuit that has only one path for the current.

400
What is a resistor?
A material that slows or resists, but doesn't stop the flow of the current.
400
What is an example of a conductor?
Several examples can be given.
400

What is an example of an insulator?

Several examples can be given.

400
What is a conductor?
A material that current can pass through easily.
400

Electric current moves from ___________ voltage to ___________ voltage

Electric current moves from HIGHER voltage to LOWER voltage

500
How do we get electricity?
When an electron moves to a different atom, it causes another electron to have to move. When electrons move quickly from one atom to another it makes electricity.
500

What is an insulator?

A material that current cannot pass through easily.

500
