How much energy is wasted for every 1000 megajoule?
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
If an appliance does not work at all when you plug it in and turn the switch on the appliance circuit is what?
The appliance's circuit is open.
How do you interpret a sankey diagram?
It is a means of saying how much energy is useful and wasted. Has the appliance represented on the diagram got a high or low efficiency; i.e, is there a larger proportion of useful energy compared to that of wasted energy, making the it more efficient. Can you work out the efficiency as a percentage using your knowledge of the equation, Efficieny = useful energy out/ total energy in?
What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
What is meant by rating of electrical appliance?
possibly an efficiency rate on a scale that isn't presented on the appliance
What is the efficiency of propane for space heating?
The efficiency of the fuel is determined by the appliance that is burning it, not the fuel itself.
Does shortening the power cord improve operational efficiency of an appliance?
No
Are fossil fuels efficient?
It depends on the efficiency rating of the burn appliance.
How do you know how many amps an appliance is using?
If the appliance tells you how many watts it's supposed to use you can buy a watt-meter to measure how many watts the appliance is using buy plugging in the meter into the wall and then plugging the appliance into the meter. A popular brand is "Kill A Watt", it meter can be bought on E-bay for under $25.
What does the power rating for an appliance tell us?
How much energy it uses

What happens when a 2A 220 volt appliance is plugged into a 110 volt?
Not much of anything. The 220 volt appliance needs just that ... 220 volts in order to run. If it runs at all, it certainly would not be running at anywhere near peak efficiency.
How can you calculate the efficiency of an appliance in terms of power?
vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100
How do you tell a frigidaire refrigerator year?
It's in the ser.# - but I have to see it to tell which year. Any appliance parts store can tell you if they see full ser.#.
How do you replace the plug on an appliance?
Plugs/cords can be purchased from appliance parts stores like www.appliancepartspros.com. Usually on the bag it will tell you how to replace. It is usually just a couple of screws.
How can you tell if its frost free?
A frost-free appliance has a built-in heating element that automatically melts any frost buildup. You can tell if an appliance is frost-free if it does not require manual defrosting and has a vent or drainage system to remove melted frost.
