Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.
. The heating appliances has a heating element like resistors. The resistors convert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity.
Those devices who produced heat, the Nichrome wire is an element who is responsible for heating . when we say nichrome wire , it is an alloy with the combination of nickel and chromium . It has two reasons why it serves as a good producer of heat.
First, Nichrome wire has greater resistivity than the other element like cooper.Second,it does not rust even at high temperature.
therefore, when electrons collide with atoms, they make the latter turn and vibrate even faster. In that case more thermal energy may produced.
When the wire resistance is greater,The hotter the object becomes .
