why is the element at the bottom in an electric Kettle?
- MidatlantianLv 71 decade agoFavorite Answer
The element produces heat, which heats the water in contact with it.
When the water is heated, it rises, and cooler water moves down into contact with the element. This turns out to be a very efficient way to heat all of the water in the kettle.
If you tried to heat from the top, you would find that the water in bottom of the kettle would remain surprisingly cool.
And of course, if you did not fill the kettle, an element near to top would not be in contact with the water at all: it would get hotter and hotter, and finally burn out or melt.
