What is a circuit?
A complete pathway or loop for electricity to flow
|
What is an energy source?
Something such as coal, wood, oil or gas used to make electricity
|
What is a switch
Something you use to turn a light or other equipment on or off with
|
What is an insulator
Something that electricity CAN NOT flow through
|
What is a closed circuit?
A complete pathway that lets electricity travel without being turned off and on
|
What is a filament
A thin thread that becomes very hot and lets off light as an electric current runs through it
|
What is a system
When you put a lot of things together to work as one thing ( a set of interacting parts that work together to form a unified whole)
|
What is a conductor
Something that electricity CAN flow through
|
What is an open circuit?
An incomplete pathway or loop that can stop the flow of electricity (it can be turned off and on)
|
What is light bulb
Something that gives off light as an electric current is going through a thin filament that glows with a lot of heat (we put them in lamps)
|
What is a turbine
Something that has a lot of blades that is turned by a liquid and as it turns, it changes machine made energy into electrical energy
|
What is a nonrenewable resource
Things that people use from our earth/world for energy that cannot be put back and we are running out of them such as coal, oil and gas
|
What is a short circuit?
What happens when an electric current flows along the wrong path (the electricity goes somewhere that it wasn't supposed to go)
|
What is fuel
Something that can be burned to make heat or power
|
What is a generator
Something that is used to change machine energy into electrical energy by passing magnets through an electric field
|
What is a renewable resource
Things that people use for energy that we never run out of because they are always there naturally like wind, sun (solar power), and water (hydropower)
|
What is an electrical pathway
Something that is used for electricity to flow through, usually a wire
|
What is electrocute
To kill or be seriously injured by an electric shock; something that is dangerous and can cause harm or serious injury
|
What is a hazard
A danger or risk. Often time with dangerous electrical areas, you will find a sign that displays this
|
What is a myth
A story that was made up to explain something that people didn't understand. The story is not true. It is called a
