no. it means that the kettle can be unplugged from the electricity source. the heating source is in touch with water, as it is located inside the kettle :)
a kettle is made out of metal
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
someone pls say the answer to this cuz i need it ;-;
it won't get as hot
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.

There are several English words spelled "element". The Japanese equivalents are:youso (element as in a part of a complete item, job or process)genso (chemical element)hitasoshi (heating element in a kettle)
the heating element turns black because it heats up all the water xxxx I think this is likely to be because your water supply is acidic (pH less than 7). This can dissolve the element over time. Probably best to replace the kettle with one with a concealed element.
There is a heating element in the kettle. As the water boils, the inner temperature of the kettle rises. Once the boiling temperature is reached, a small thermostat is triggered which turns the kettle off, so as to not boil continually. This thermostat works optimally with the lid on the kettle fully closed, if the lid is not fully closed, it does not switch the kettle off as quickly.
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.
When you put the switch on, the electricity goes thought the wires heating the melt prongs, which heats the kettle and the water. When you put the switch on, the electricity goes thought the wires heating the melt prongs, which heats the kettle and the water.
You can use the cordless kettle to first boil water and then make the coffee in a cup. But if you make the coffee directly in the cordless kettle, it will make a mess and be very difficult to clean all the coffee grounds from it. It is better to use the kettle only for boiling water and nothing else- this way it will stay clean and last longer.
