A typical electric oven has a heating element, a length of metal that acts as an electrical resistor. As electrical current passes through, the heating element becomes hot.
The oven will either be a convection oven or not. A non convection oven relies on the heating element warming the air, and this in turn warms the food. A convection oven uses circulating air inside the oven. Circulating the air causes faster heat transfer from the heating element to the air, and faster heat transfer from the air to the food than with simple heat conduction only.
electricity. (that's why they call it an electricoven!!)
ovens produce heat my an electric charge of the battery that contains hot air and makes the oven hot and to heat your food
electric, but it alot of times depends on the stove quality.

Yes.
An electric double oven and an electric single oven would have about the same capacity. The only difference between the two is that you can cook two things at the same time with different temperatures using the double oven. It may even heat up faster as well.
Gas ovens do save more money than electric ovens. But the drawback to a gas oven versus electric is that you do not get even heat exchange with gas as you do with an electric oven.
GE and Hotpoint brands come in electric, and there are several private-label brands as well.

This would depend on the manufacter of the oven and what temperature you have it set to but it can typically take 20 - 30 minutes to fully heat up.
Light energy from IR rays to heat energy into water droplets in the oven
the bottom of the oven.
If the food directly touches something (e.g. pan, oven grate, oven walls, red hot electric element) heat is transferred by conduction.
If the oven has a built in temperature gauge, then you should read that for the correct heat. If it does not, I suggest you buy a thermometer that is made to withstand oven heat and use that to tell when it is hot enough.
