Linda asks…
What are some energy transformation devices?
For my physics investigation i have this question:
Identify the various energy transformations by which electrical energy can be produces from other forms of energy.
I got: Chemical energy to electrical energy
Sound energy to electrical energy
Gravitational potential energy to electrical energy
Mechanical energy to electrical energy
Heat to electrical energy
Wind energy to electrical energy
Kinetic energy to electrical energy
Strain to electrical energy
Radiation to electrical energy
Light energy to electrical energy
then theres the question:
Name some of the technological devices that employ each method.
I’ve looked around but I only got battery, Fuel cells, microphone, telephone, transducer, solar panels, solar cells, turbine, motor.
What are some others for each point in the first question?
admin answers:
There are many different machines and transducers that convert one energy form into another. A short list of examples follows:
Thermoelectric (Heat → Electric energy)
Geothermal power (Heat→ Electric energy)
Heat engines, such as the internal combustion engine used in cars, or the steam engine (Heat → Mechanical energy)
Ocean thermal power (Heat → Electric energy)
Hydroelectric dams (Gravitational potential energy → Electric energy)
Electric generator (Kinetic energy or Mechanical work → Electric energy)
Fuel cells (Chemical energy → Electric energy)
Battery (electricity) (Chemical energy → Electric energy)
Fire (Chemical energy → Heat and Light)
Electric lamp (Electric energy → Heat and Light)
Microphone (Sound → Electric energy)
Wave power (Mechanical energy → Electric energy)
Windmills (Wind energy → Electric energy or Mechanical energy)
Piezoelectrics (Strain → Electric energy)
Acoustoelectrics (Sound → Electric energy)
Friction (Kinetic energy → Heat)
