Electricity, Sound, Solar System

What kind of circuit is this?

• series
• parallel

If bulb 1 burns out, what will occur?

• bulbs 2 and 3 will go out
• bulbs 2 and 3 receive more volts
• bulbs 2 and 3 will stay lit
• nothing will happen

A material in which electrons are not able to move easily is called _______.

• Circuit 
• Insulator 
• Resistance 
• Conductor

This image represents what type of circuit?

• open
• wire
• series
• parallel

This is the symbol for a _____?

• switch
• light 
• battery
• wires

What is this symbol for?

• light bulb
• switch
• battery
• resistor

In a series circuit  with 4 bulbs:

• a switch is never used
• all of the bulbs become dimmer if another bulb is added
• There are many paths for electricity to take
• the remaining 3 bulbs stay lit if one burns out

An example of a conductor is :

• a glass paperweight
• a plastic cap
• a metal screw
• a wooden handle

All wires used in electric circuits should be covered with:

• a colored material.
• a conducting material.
• an insulating material.
• none of these.

What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not
• A conductor allows electricity to flow through it easily and an insulator does not.
• An insulator is magnetic and a conductor is not
• A conductor is magnetic and an insulator is not
