What is ELECTRICITY?
The flow of the sun's energy.
The flow of positive charges (protons)
The flow of negative charges (electrons)
The flow of energy from lightbulbs
What happens when you have an OPEN circuit?
You have a complete path and the lightbulb will work.
You have a break in the path and the lightbulb will not work.
You have only one path and the lightbulb will work.
You have more than one path and the lightbulb will not work.
What is a CLOSED circuit?
A complete path for the electrons to flow
A break in the path for the electrons
Many paths for the electrons
Something that will turn on and off the electricity
Why do we use switches in a circuit?
Because they're cool
So we can change the direction of the electrons
It makes the current stronger
It opens and closes the circuit
