What is the efficiency of a motor that converts 100J of electric energy into 70j of useful energy?
70% efficient Take: Useful work out --------------------- X 100 = efficiency Work in
Why is work the output always less than work input?
Except for a technical joke about electric heaters (all the losses are heat) some energy is always lost due to friction (or its equivalent), The word is entropy.

What type of electric element do electric heaters use?
It depends on the size of the element in the heater. It should say what its rating is on the appliance. If there is no rating then the best way to work it out is to turn everything else off and see how much the electricity meter registers in one hour. If it is 2 kilowatts for instance then then the element is 2000 watts and you know it will use 2kw per hour. This assumes it won't be turned on and off by its thermostat which normally happens as it reaches it's final temperature.
Is electric heater require oxygen to burn?
No, electric heaters work by running electric current through resistors which produces heat. same as an element on an oven range top.
Are Tankless Water Heaters more efficient than regular water heaters?
Tankless water heaters are more energy and cost efficient than your typical water heaters. Of course, each person has their own needs and it is always a good idea to weigh out the pros and cons before making any decisions for a change. What works well for some may not work well for other.
Are there energy efficient sash windows?
Yes, I have found energy efficient sash windows at www.boxsash.com in the UK. In the USA I located energy efficient sash windows at http://www.fjbassociates.com/work/untitled/windows.html.
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.
What is able to work well without wasting energy?
efficient
How does an electric switch heater work?
The electric switch heater uses high voltage, from 480 to 750 volts, through coils that are fixed both on the web of the rails and with "crib heaters" that are laid underneath the movable rods between the ties. These are typically more effective than other types of switch heaters because of the ability to provide the crib heaters, which cannot be used with gas heaters. The heating elements are provided throughout the area of the movable parts of the switch layout.
An electric motor turns energy into what?
work
Radiant Heaters More Energy Efficient Than Forced Air Heat?
Radiant heaters supply heat directly to the ceiling, floor or walls of a home. They use radiant heat transfer, which is heat moving directly from the hot surface to the objects or people in the room. This is the same effect as when you can feel the heat of stove burner from across the room. This type of heating is more energy efficient than forced-air heat because no heat is lost in the duct work. Since there is no moving air, it is better for people with allergies.
