Does a wire in an electrical cord of an electrical kettle have a higher or lower resistance than the heating element inside the kettle?
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.
What elements are used in an electric heater filament?
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.
Why would a home heater be blowing cold air?
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.
What element is in the heating element for toasters?
That would most likely be a nickel and chrome alloy. Light bulbs use tungsten.
What would cause a 1996 Mitsubishi Galant to have no heat?
heating element stopped working
Is it possible to create your own little battery-operated heater?
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.
What will happen if the heating element is near at the top of the kettle?
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.
What would cause a burning smell in a 2003 Honda Element?
Your car may be on fire.
What will happen if a element burns?
"Burning" in the conventional sense is combining with Oxygen. The element would liberate heat and leave as residue, oxides of itself.
When heating sulfur what reaction physical or chemical?
Heating S in a closed environment where it reacts with nothing would be physical but burning S in an open environment it will react with O and is therefore chemical.
Which type of substance would you use as a heating coil in an electric toasters?
I believe I would select NiChrome wire. It has a high resistance for a metal and is not particularly toxic or expensive.
What would affect the brightness of a lamp?
Voltage applied (voltage at source, resistance of wire and conections etc), ground resistance, designed brightness of element in comparison to the applied voltage
