In that case, it would be less efficient. Hot water rises to the top, mixing the water (if the heating element is at the bottom). When it is at the top, the water won't mix as well, and more heat would be wasted.
Tungsten is not commonly used as a heating element in iron boxes because it has a very high melting point, which would make it difficult to work with and shape into the required size and configuration for the heating element. Additionally, tungsten is quite expensive compared to other materials commonly used for heating elements, making it less economical for this application.
The heating element in toasters typically consists of a resistance wire made from a material like nichrome. This metal alloy is chosen for its ability to efficiently convert electrical energy into heat, allowing the toaster to quickly and evenly toast bread.
The heating element in the electric kettle will be primarily pure resistive. Power in that case is calculated P = E*I = 250V*I = 3000 W So the current is I = 3000 W/250 V = 12 Amps If there is anything else (lights, radio, PC, etc.) on the circuit that may be taking some current you are very likely to go over 13 A frequently. I don't know how accurate you can expect a fuse's blow point to be. Perhaps +/- 10%? Doesn't seem very trouble free. Even if the circuit is dedicated to the kettle, consider this idea. We don't know exactly what conditions the manufacturer was considering when specifying the wattage. Probably operating conditions, when the element was hot. Then Ohm's Law tells us that the resistance R is R = E/I = 250 V/12 Amps = 20.8 Ohms But the element's resistance would be lower at first when it is cold. My calculations indicate that if the element is made of nichrome wire, and if the temperature change is 200 degrees C, the hot resistance of 21 Ohms is probably about 1.7 Ohms higher than when at room temperature. If that is true, when you first turn it on, Ohm's Law says that the initial current should be 12.95 Amps. Regardless of this analysis, remember that the fuse requirement is based on the size of the wires in the wall. You don't want those wires to get hot. Don't put in a bigger fuse than what was there originally.
Only the fan is working, there is no gas burning (gas heater) or the electric heating element is not working(electric heater)Answeris it electric gas or oil Its gas.
The heating element in electric heaters and irons is made from an alloy of nickel and chronium called nichrome. It is usually made in the form of wire. The wire is often wound around a flat sheet of mica for support. Mica is a thin layered mineral that can withstand high temperatures.
For two 4500W heating elements, you would typically require a double pole 20 amp breaker for each element. This would provide adequate protection for the heating elements and ensure proper functioning of the circuit.
Placing the heating element at the bottom of the kettle allows heat to be directly transferred to the water, resulting in quicker and more uniform heating. If the heating element were in the middle, the water at the top of the kettle would take longer to heat up and there could be hot spots in the water.

Your car may be on fire.
It is possible. With a battery power source and some kind of heating element that creates electrical resistance in order to transfer that energy into heat; it could be done. I would not recommend that you try.
"Burning" in the conventional sense is combining with Oxygen. The element would liberate heat and leave as residue, oxides of itself.
