Does a toaster use nuclear energy and how?
A toaster converts electrical energy into thermal energy. Some of that electrical energy may have come from a nuclear power plant.
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 electromagnetic waves does a toaster use?
infrared radiation:)
What are the two electromagnetic waves does your toaster use?
Toasters and incandescent (old fashioned) light bulbs are very similar devices.Both of them use electric current passing through a wire to make the wire emitheat and light. In the light bulb, we use the light, and the heat is a nuisance.In the toaster, we use the heat, and we don't much care about the light.
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.
Do non-electronic toasters draw power when not in use?
yes they do, in fact the toaster draws power more when it is not in use

Why do people use the toaster?
people use the toaster oven to toast bread.
What is the source of power for the toaster?
electricity??
What consumes more power a light bulb or toaster?
By far a toaster draws more current than a light bulb.
How many kWh does a toaster use a year?
That depends a LOT on its power rating, but especially on how many minutes you use it every day, on average. Look at your toaster - electrical equipment usually has a power rating. If a power rating in watt is not given, you can multiply volts x amperes. If it says something in watts, convert that to kilowatts. Make an estimate, how many hours you turn the toaster on in a year. Multiply the kilowatts x the number of hours.

When you use a toaster why does toast pop up and the bread disappears?
Magic. The toaster eats it. Bad toaster.
what is the power source to assemble a toaster?
AC supply of 220V for domestic use. So appliances normally have the range of 220Vac - 240Vac.
How many watts is a toaster?
You can usually find the number of volts (and watts) on a sticker under your toaster. My toaster can hold 4 pieces of toast, and uses 120 volts, but it will vary for different toaster companies, and sizes of the toaster.
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.
