 Repel

100
What is the flow of electrical charges called?
An electrical current
200
Electric charges can build up on objects rubbed together due to fr________.
Friction
200

What is a current? 

The flow of electrons 

200

True

200

A tool used to measure two or more electrical values—principally voltage (volts), current (amps), and resistance (ohms).

A multimeter

300
Name three examples of conductors of electricity.
Copper, metal, or silver.
300
What kind of circuit is it if the electric current does not flow through the circuit? O_______ circuit
An open circuit.
300

The space around an electric charge that causes them to attract and repel is called

Electric Field

300
This is a measure of how much energy can be given to the moving electrons in a circuit. Hint: ________e
Voltage
400
Name three types of insulators (these don't conduct electricity easily).
Rubber, plastic and glass.
400

If the voltage stays the same, but the resistance goes up the current will?

decrease (slow down)

400

Name two electrical devices that change electricity into motion.

Anything with a motor: a fan, a vacuum cleaner, for example.

400
If a balloon has more positive charges than negative charges, it is considered to have what kind of charge?
A positive charge.
500
The build-up of electric charges on an object is called: s_________ e___________
Static Electricity
500
In a series circuit, if one bulb burns out - will the current flow in the circuit? Yes or No?
No. If any part of a series circuit is broken or removed, the circuit is open and will not flow.
500

What determines the charge of a substance?
