Static Electricity
What type of charge does an electron have?
Negative
What happens when two positive charges are brought together?
They Repel each other
What device opens and closes a circuit?
A switch
Name one material that is a good electrical conductor
Metals of any kind
What part of a circuit provides the energy?
The battery
What is the cause of a charge to build up on an object? (What is happening on the atomic level?)
Transfer of electrons
What happens when a positive and negative charge come near each other?
They attract each other
In a Series circuit what happens when one bulb goes out?
The whole circuit stops working, no flow
Why is rubber used around electrical wires?
It is an insulator preventing people from getting shocked
What device changes electrical energy into light energy?
A light bulb
When you rub your hair on a balloon, it could stand straight up? Why might this be?
Electrons transfer from your hair to the balloon causing attraction.
What happens to electrical force as charges move farther apart?
It gets weaker
What type of circuit has more than one path for electricity to follow
A parallel Circuit
Would a plastic spoon be a conductor or insulator?
Insulator
The most common way to build up a charge for static electricity is what?
Friction
What is grounding?
Removing charge safely or returning the charge to neutral
This particle is able to transfer from one atom to another. It is what moves through wires in a circuit
An Electron
Why are most homes wired with parallel circuits rather than series circuits?
So you can turn off one path and not affect the others
Why can birds safely sit on power lines?
The lines are insulated with rubber coverings
Oh no! A cute woodland creature, possibly a mouse, chewed through a wire on a simple circuit. What would happen to the energy flow and lode on this simple circuit
There would be no flow, and no energy powering the light bulb
Explain how lightning is related to static electricity
It is a discharge from differing charges in the clouds and the ground
The van de graff machine spreads static electricity by building up charge on contact through what method?
Conduction
Explain the difference between static and current electricity
varied response
Name two insulators
varied non metals
Why would a balloon charged with static electricity attach to the wall and stay there if the wall has neutral charge. Hint, how can things be charged
Explain temporary charge or induction
