Heat is produced in electric generators due to what?
"friction"
Is a generator a electromagnet?
Electric motors and electric generators can have permanent magnets or electromagnets. It depends on the design. For example electric generators can be dynamos, alternators, or rotary converters. However, in general electric motors are electromagnetic so that resistance disappears when current is cut and electric generators have permanent magnets.
Are magnets inside electric generators small enough to be turned by hand?
It depends on the size of the generator. In large ones, like the type that power cities, no. But small generators exist that can be powered by hand, like those found in emergency radios.
What is the Cost of a whole house generator?
Emergency power generators range in price from $2,500 to $9,000 depending on the capacity and options you want.Emergency home generators run on low pressure gas or natural gas. The sizes of these generators range from 8 to 125 kilowatts. With these generators a transfer switch will automatically turn on the generator when there is a power outage and return back to standard electric power when the electric is restored.FOR MORE INFORMATION AND VIDEO GO TO:http://www.emergencysuppliesinfo.com/whole-house-generators.html
What are the key features of a generator?
There are several types of generators, electrical generators, vapor generators, motion generators (also called motors). Let us concentrate on electrical generators used to transform some natural energy (e.g. chemical energy in oil, kinetic energy of a cascade, chemical energy in methane, thermal energy in solar light etc..) in electrical energy that can be transmitted on long distances via electric trunks. The main parameters of such a generator are - Efficiency: that is what percentage of the incoming natural energy is transformed in electrical energy (ranging from 3-35% of oil based generators to 20 % in nuclear generators) - Dimension: that is how much energy per hour (measured in MW/h or GW/h) is obtained from the generator; - Generated pollution (that can be measured in many ways depending on the generator: Co, CO2 and heavy pollution for oil based systems for example)
Can electric current be generated by magnetic force?
Yes. That's how generators work.
Explain why electric motors and generators are opposites?
Electric motors take electric energy and turn it into kinetic energy Generators take mechanical energy and turn it into electric energy
What do electric generators and electric motors have in common?
Stator and rotor
What are the main ways we produce electricity in NZ?
Hydro electric generators wind powered generators geothermal generators
Who sells electric generators?
You can find electric generators in stores like Lowes and Sears. You can get help at the store for choosing the right generator for yourself. The generators available can be researched more for reviews and selected.
What are examples of electric generators?
A dump in the toilet
What was Michael Faraday among the first to build?
electric genearator
What is different about gas powered generators?
Gas powered generators require a supply of gasoline or propane to be able to power your things. Electric generators charge themselves up from your electricity so they wouldn't work as long. You could find out more about them from a store that sells them.
Where is it possible to purchase an electric generator?
Stores such as Walmart, Home Depot, Sears, and WayFair. There are a few stores like Overstock and Electric Generators Direct that sell electric generators for low prices.
Where can one buy a portable electric generator?
Portable electric generators can be purchased from many company's on the internet. A few of the company's that will stock portable electric generators are eBay,Amazon and Best Buy.
What do generators and motors have in common?
Electric motors and generators are electromagnetic devices that are the opposite of each other. Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.
