Your hair or wool

What is a good object or material to rub a balloon against to charge the balloon with static electricity so it will stick to the wall?

A material that allows electrons to flow easily

What is a conductor?

One

How many pathways are there for the electricity to flow on a series circuit?

A switch

What is commonly used to turn electrical current on or off?

C: The light bulbs will shine brighter

If you add more batteries to an electrical circuit, what will happen to the light bulbs on that circuit? a. the light bulbs will last longer b. there will be no change c. the light bulbs will shine brighter

True

True or False? Rubbing a piece of plastic with a piece of wool will generate static electricity?

A material that allows little or no electrical flow

What is a nonconductor?

Parallel

Do lights shine brighter on a series circuit or a parallel circuit?

To prevent the circuit from overloading

What is the job of a fuse on an electrical circuit?

Copper wires, an energy source (example: battery), load, switch, fuse

What are the different parts needed for a circuit?

repel

Two objects that are both negatively charged will ____________ each other.

Wet

Almost any object becomes a good conductor when it is ________.

All of the lights will go out because it is no longer a complete circuit.

What happens if one light bulb burns out on a series circuit?

Closed

On a complete circuit, is the switch open or closed?

Ammeter

What device measures how much electricity is flowing through the wires at one time?

You can see light (if it is dark) and you can feel a shock. Bonus Question: What is a natural example of a very large static electrical discharge?

How can you tell when static electricity has been discharged?

Conductors!

Are the materials on this list conductors or nonconductors? - salt solution - carbon - graphite - copper wire - aluminum - silver - impure water - zinc - most metals

The other lights would still light because the current still has a complete pathway to follow.

What would happen if one light bulb (out of many) on a parallel circuit burned out?

The metal strip (the fuse strip) breaks, or melts, and the flow of electricity stops because the circuit is no longer complete.

Explain what happens to a fuse when the electric circuit is overloaded.

Snap, toggle, or wall switch

What is most likely the most common type of switch in your home or in our school?

Some possible answers: - your hair stands up after you comb it - your hair stands up after you go down a plastic slide - you feel a little shock as you put your hand on the door knob after rubbing your stocking feet on the carpet - your clothes "stick" together as you take them out of the dryer

What is an example of static electricity in everyday life?

Nonconductors!

Are the materials on this list conductors or nonconductors? - silk - plastic - rubber - glass - diamond - wool - wood - fur

A parallel circuit. This is so the lights and all things that require electricity can have their own complete path of electricity and continue running even if one light burns out.

Are the lights in your home most likely on a series circuit or a parallel circuit? Why?

At the terminals

Where do electric wires connect to a switch?

Burning fossil fuels, wind energy, solar energy, nuclear energy

What is an example of a power source that is not a battery?
