HEAT GENERATED IN APPLIANCES 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 resistorsconvert 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
