How does the electric kettle work?

Answer 1

Electricity travels through the element inside the kettle, but resistance to the flow of electricity causes heat. The heat is then conducted into the water. When the water reaches boiling point, the steam heats up a 'Bimetallic Strip' which is made up of two different strips of metal, which bends because one of the metals expands faster than the other. This breaks the circuit, and the electricity doesn't get through the element until the bimetallic strip has cooled down.

Answer 2

An electric kettle, common in Canada but not in the U.S. works by having a double bottom. An electric heating element is contained in between the inner metal container and outer bottom of the appliance. Water never touches the actual element and a thermal cut off switch turns the element off when the water boils.

Answer 3

Electric cookers work through conduction. The electric burner is heated up and a pot or pan is placed against it. This contact allows for conduction and the content in the pot is heated in the same way.

Answer 4

It is very easy if you think. First you have to soak the rice with tap water in a the bowl that comes with the electric rice cooker. pour out the water because the water can poison you. do that 5-6 times. then put your hand in to it and push it up rice up a little and squeeze it then push it back down. Then pour some drinking water in there until it is higher then the rice point than a inch. Then put the rice bowl into the cooker and close it and wait until it is done.

Answer 5

The first kettle was used over a fire , or primative stove, made of rocks.

Answer 6

Electricity heats an element in the base of the kettle, it in turn heats water around it - you soon have boiling water

Answer 7

To heat up water *facepalm*
