What is wasted energy in a toaster?
There is a lot of confusion on all matters relating to heat. The efficiency of a device is usually the fraction of consumed energy which goes into the function of the device. For an engine, this is straight-forward. For a light bulb or a toaster, not so. For light emitting devices, in the wintertime when you are heating your house anyway, the answer is 100%. None of the energy is wasted; it just replaces some use of your electric heater. But what if you have a gas heater? Then the efficiency is relative. In the summertime, this is a much more important question. For a light bulb, you would look at light output (in Lumens) per energy input (in Watts). For a toaster, the answer is *completely* relative, rather than a fraction. The pertinent question is: How much energy does *this* toaster require to toast a piece of bread, compared to another toaster. I have not found much experimentation which answers that, even to compare toasters to toaster ovens. Toaster ovens may turn off during heating, so it's not simply a matter of maximum wattage. In general, the closer the heating element is to the surface of the bread, the higher the 'efficiency' of the toaster. On thin bread, bagel toasters are thus somewhat less efficient than smaller toasters are. Cheap toaster ovens are sometimes accused of making bread 'soggy', which is a result of the bread being heated by the air rather than directly by radiation from the heating elements.
How much power does a toaster use?
actually, there is usually a sticker under your toaster. The amount of watts, and volts can change from different companies, and the size of toaster you have. My toaster can fit 4 pieces of toast and it uses 120 volts and 1500 watts
How much energy is used during 10 minutes of strenuous exercise at 500 W?
you will use 83,3 Wh..
How much power does a toaster have if it does 21000 joules of work in 30 seconds?
Efficiency here would be power out divided by power in. Energy out is 38,000 Joules. A joule is a watt X second. The toaster is on for 120 seconds. So that 316.66... watts power over the time period t(which doesn't matter). 316.66... watts/ 330 watts = 0.95959.... efficient or 96%.
What determines how much energy a human can receive from?
A human gets energy from the calories of food. how much energy the food molecules have
How much energy is used in a 4 slice toaster?
Look at the nameplate for the wattage, then observe how many minutes it takes to toast. Multiply together to get kw.minutes and then divide by 60 to get Kw.hours
If you plugged a 110V toaster into a 220V outlet what would happen to the electrical current of the toaster?
Two main differences are between 110V and 220V. One is the voltage and the other the frequency (60Hz and 50Hz, respectively). In a pure electrical (not electronic) toaster, the frequency shouldn't matter. On the other hand, if we think the toaster as a resistance heater and nothing else, then the amount of heat delivered to the toast is Q=V^2/R Since the only change in going from 110V to 220V is to double the Voltage, then we see from here that the heat will be enhanced by a factor 4. This is too much. I'd say that the wires which get red and transmit the heat would blow up if the amount of heat they deliver is 4 times what they were made for. However, this is a pure theoretical guess. In these cases nothing better that somebody who tried it tells us what happened! Ezequiel.
How much energy does a large size Oster toaster oven use?
Large does not tell us much. However the rating will be printed somewhere on the appliance.

How much force is needed to push the handle on a toaster down?
That really depends on the toaster. Try it out, with your own toaster.
How much toast could a toaster toast if a toaster could toast toast.?
It depends, how much toast do you have.... It also depends on how many toast your toaster can toast.
Can you plug two appliances a 120v and a 110v on the same line which is a 110v?
Should be ok provided you do not draw too much current.
How much energy does a toaster use?
The related link states a toaster uses 800 to 1500 watts. I make my toast in a small toaster oven, and I read on the bottom of the appliance that it uses 1500 watts. Now, energy use is measured in watt-hours. To figure out how long toast takes to cook, I put a piece of bread in the oven- it took about 4 minutes to toast, so: 1500 x 4/60 = 400 watts-hours. Now, on my electric bill, the power use is given in kilowatt hours, so I divide 400 by 1000, and get 0.4 kilowatt-hour (0.4 kwh), which isn't much electrical use. See related links.
An electric heating element is connected to a 110v circuit of a 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
110v x 3.2 a=352 watts time 5= 17600.00 watts or 353 watts per hour
A toaster on 220 V line draws a current of 5 A How much heat does it generate in 10 minutes?
First calculate the power: P = I2R. Power will be in watts. Then multiply power x time to get the total amount of energy transferred. If the time is in seconds and the power in watts, the energy will be in joules. (In this case you need to convert the time to seconds first.)
Difference between 1950s toaster and present day toaster?
Hydro was much cheaper in the 1950's :)
How much energy can you save by turning on LED light for 3 minutes then shut off every hour?
If you run it for 3 minutes and off for 57 minutes each hour, it would save 95% of the energy.
