He invented the light bulb.
Who is Thomas A. Edison
100
Another word for "electricity" is?
What is energy.
100
Static electricity is the build up of what on an object?
What are electrons.
100
Electrical appliances have 3 main purposes, what are they?
What are to provide heat, provide light and do work.
100
What is the equation for measuring electricity?
What is Energy = Power x Time. OR What is Kilowatts X Hour.
200
He found out voices could be sent through a wire.
Who is Alexander Graham Bell
200
Animals use electricity in many ways. Name 2 examples.
What are electric eel - shocks for defense and hunting, sharks - sense electrical fields, catfish - sense electrical fields/uses electrical field to detect objects, playtpus - detects electricity in other animals, oriental hornet - uses solar energy. ETC.
200
How is lightning static electricity?
What is the air rubbing against the rainclouds building up the negative electrons. These negative electrons find the quickest way to a neutral/positive atom and the flash is the electrons travelling.
200
What are the 4 types of Electrical Injuries?
What are, electrocution, electric shocks, thermal burns and falls.
200
My ipod player runs on 30W/h of energy. How long would it take me to use a KWH?
What is 33.33 hours.
300
Benjamin Franklin invented this device to protect houses from burning down.
What is the lightning rod.
300
The electricity in the human body runs through these wire-like things to help us move.
What are nerves.
300
What happens in the air in the winter to make you feel more static then in summer?
What are slower moving electrons in the winter and less moisture in the air to help transfer those electrons.
300
Why are humans such good conductors of electricity?
Our body is made of 70% water and electricity flows through water very easily.
300
Which direction do we read an energy meter?
What is right to left.
400
Messages sent over great distances are called?
What are telegrams.
400
The majority of the world produces it electricity through this source.
What is coal.
400
How does a Van De Graff Generator work?
What is a turning belt building up negative electrons and distributing them onto the ball. When you touch it these electrons build up on you, making your hair lift and oppose each other.
400
Why is a person told to rest if they have been electrocuted but are conscious and seem unharmed?
There are chances of internal burns, a possible heart attack risk and other unseen injuries.
400
James checked his meter two days in a row and on the first day it read 44321 and the second day it read 49345. In his town energy costs $0.012 per kwh. How much did it cost him over that day?
What is $60.28
500
This device opened the door to the first silent movies.
What is the vitascope.
500
Name 4 renewable sources of producing electricity.
What are wind generators, solar energy, tidal power, geothermal sources and hydroelectric.
500
How could you make a balloon stick to a wall?
What is rubbing a balloon on your head to build up the negative electrons and touching it onto a positive wall. They will attract to each other.
500
Why don't birds get shocked when they sit on power lines?
Birds are only touching one wire, if they touched a second wire they would get electrocuted. It is much more efficient for the electricity to continue going through the wire instead of flowing through the bird.
500
Chris checked his meter two days in a row and on the first day it read 61437 and the second day it read 62371. In his town energy costs $0.010 per kwh. How much did it cost him over that day?
What is $9.34.
