You would top-broil in a stoves broiling drawer if it has a flame or electric heating unit above it. You can also use an electric toaster/oven/broiler with a broil setting for an overhead heating element.
Sink in what water? Well, not taking in account that the electric wires in the toaster shouldn't be immersed in water, a toaster would sink because its density is greater that of water. Had it been less the toaster would float.
I believe I would select NiChrome wire. It has a high resistance for a metal and is not particularly toxic or expensive.
Toasters are not designed to cook sausage or any other type of meat. The fat in sausage would drip on the heating elements of the toaster and cause a fire. So, in effect, you better have house insurance...
The earth wire would typically be connected to the metal casing of the toaster. This is to provide a safe path for electric current to flow in case of a fault, protecting users from electrical shock.
Heating up by putting in energy (heat)
Research has not provided any conclusive evidence as to why an electric heating system would be more reliable than a gas heating system. It is believed that both are equally reliable, and for cost efficiency it is quite a bit cheaper to heat with gas than it is with electric heat.
Copper is a good conductor of electricity, making it ideal for transmitting the electric current in a toaster efficiently. Additionally, copper is durable, heat-resistant, and readily available, making it a cost-effective choice for toaster wiring.
Wasted energy in a toaster typically comes from heat loss through the toaster casing, radiant heat that escapes into the surrounding environment, and electrical energy converted to heat that is not used for toasting the bread. To reduce wasted energy, you can minimize the time the toaster is left on when not in use and consider using a toaster oven instead, which may be more energy efficient for certain tasks.
thermocouple
If Sparky crossed the wires of his electric blanket and toaster, there would likely be a short circuit, leading to a potential risk of electric shock, overheating, or even fire. It is extremely dangerous to mix different electrical devices in this way, so it should be avoided at all costs.
Yes a heating coil is a conductor of electricity, other wise it would not heat up.
