Lesson 1
What is the charge of a proton?
Positive
The rate of flow of electric charges
Electric Current
A complete path though which electric charges can flow
Electric circuit
What is an example of a power source?
Battery
What is the charge of a neutron?
Neutral
In this type of current, charges always flow in the same direction
Direct Current
In this type of circuit, all the parts are connected in a row that forms one path for the electric charges to follow.
Series Circuit
What is an example of an electrical conductor?
Copper wire, water
What is the charge of an electron
negative
In this type of current the charges repeatedly shift from flowing in one direction to flowing in the reverse direction.
Alternating current
In this type of circuit, electric charges have more than one path that they can follow.
Parallel circuit
What is an example of an electrical insulator?
Glass, plastic, rubber
What kind of charges attract?
Opposite
What is an example of alternating current?
A light plugged into an outlet
What is the name of the electrical safety device that acts like a switch when the current is too high in a fuse?
Fuse, circuit breaker or GFCI
What is an example of a load in a circuit?
Lightbulb, computer, radio
Extra positive or negative charge that builds up on an object
Static Electricity
What is an example of a direct current?
A battery in a flashlight
How does a lightning rod protect a building from lightning damage?
The rod is connected to the ground by a thick conducting wire, which grounds the charges from the lightning.
Name two energy sources the can power a house
Power plant, solar panels
