True or false. Electrical systems have an unlimited supply of energy.
false
How did you know Ergstown had a Blackout problem?
The lights went out in the buildings and the streetlights then the lights turned back on.
What is an energy converter?
something that changes one form of energy to another form of energy
to blow air
What happens when you add another more buzzer to the simple buzzer system?
The system would work but there would be less energy. The sound would be weaker.
What was Ergstown's problem?
They keep getting blackouts.
What is function?
What is another simple system you built other than a fan?
LED light ,buzzer
What happens if two or more buzzers were added to the system?
The system would not work because there is not enough energy to support.
What is the best possible solution to solve Ergstown Blackouts?
replace older streetlights with LED streetlights
Give an example of an electrical device?
What is the input energy form in the flywheel system?
electrical
What did the water model experiment demonstrate about energy in an electrical system?
All electrical devices need a certain amount of energy to work.
Why is the solution the best for Ergstown Blackouts?
Replacing older streetlights with LED streetlights doesn't change how people use their devices. Also it uses less energy to produce light energy.
Give an example of an energy converter?
streetlight, train, car, fan
What is the output of energy form in the flywheel system?
motion
A heater converts what kind of energy to what other form of energy?
electrical energy to thermal energy
What evidence did you use to support the solution?
In the sim, it showed that the LED produced more light energy than a lightbulb. The lightbulb produced more thermal energy than light energy.
