An electric motor produces 2 horsepower at an efficiency of 80 percent what current does it draw from a 220 volt line?
P = iv
Are electric heaters 100 percent efficient?
No. Nothing is 100 percent efficient. In any situation some energy will be given off in a form that is useless to us.
What temperature is required to transfer waste heat to the environment for an heat engine to be 100 percent efficient?
273k
Is edenpure a efficient electric space heater?
Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.
Why are electric heaters 100 percent efficient?
All the power absorbed by the heating element and the connecting wire is converted into heat, leading to the 100% efficiency figure.
How many percent efficient is the nuclear power plant?
Approximately 33%, depending on the design. That's measuring from reactor thermal power to final electric power.
What furnace is 98 percent efficient?
Lennox top o the line furnace is 98.2 percent efficient
Can a device be 100 percent efficient when it comes to heat transfer?
Only if you're referring to an electric heater ... since all loses are also heat. The real world answer is no.
Is a nuclear generator 100 percent efficient?
No, no machine is 100% efficient.
How efficient is a small space heater?
it is not very efficientAnswerThey are 100 percent efficient.
Is Gas more energy efficient for Cooking?
Gas cooking should be more energy efficient than electric, as the thermal energy from burning the gas goes directly into the food in the pan, whereas if the gas is used in a power plant you probably lose about 60 percent of the energy, only 40 percent goes into making the electricity
Is it better for a machine to be 25 percent efficient or 75 percent?
75 %
What is the percent efficiency of a 60W light bulb that produces 6W of light energy?
If you're using it to generate light, 10 percent efficient. If you're using it to generate heat, 90 percent efficient.
