What is rubber (insulator)
200
A __________ circuit will result in all bulbs going out, if one goes out.
What is a series?
200
A battery or other source of current MUST always be a part of an electric circuit?
What is True?
200

Give one way to decrease the brightness of a lightbulb in a circuit.

Add resistance, decrease the voltage or number of batteries.

300
What is the purpose of the rubber on the outside of a copper wire within a circuit?
What is to serve an an insulator for our protection?
300
This material allow electricity to flow through it easily.
What is a conductor?
300
This circuit is made up of more than one path of electricity?
What is parallel?
300
You must have a switch to complete a circuit?
What is False?
300

A temporary magnet created by passing electricity through a coiled wire.

What is an electromagnet.

400
The purpose of the switch is to?
What is turn the power on and off?
400
This material DOES NOT allow electricity to flow through it easily?
What is an insulator?
400

A _____________ circuit will keep the other bulbs lit, if one light bulb goes out.

What is parallel?

400

Increasing the number of wires in a circuit increases the brightness of the lightbulb.

False

400

Increasing the voltage does this to an electromagnet.

Makes it stronger.

500

If the switch in a circuit is open, will the light bulb light up? Why or why not? Give details.



No, the electrons cannot make it through the circuit.

500

Identify two conductors and two insulators.

metals, water

plastic, rubber, glass, ceramics, etc.

500

These circuits are used in most houses and buildings. Also, explain why they are better than the other type of circuit.

What are parallel circuits?

They provide a continuous source of electrons because multiple pathways for the electrons to travel are present.

500

Resistors stop electrons from flowing through a circuit.

What is false

500

Increasing the number of coils on the electromagnet does this to the magnet. 

Makes it stronger.
