Detailed explanation-1: -The toaster consist of the heating element. When electrical energy passes through this heating element, it converts this electrical energy to heat energy which helps to prepare toast (bread that turns brown on exposure to heat). Hence electrical energy is transformed to heat energy in a electric toaster.
Detailed explanation-2: -Infrared radiation emitted by the heating element is the primary mechanism for transfer of heat in a toaster oven to food. When radiation strikes a substance, its energy agitates the substance’s molecules, making it hotter. Convection toaster ovens continue to gain market share.
Detailed explanation-3: -Each heating element in a toaster typically consists of a flat ribbon of Nichrome–an alloy of nickel with chromium and sometimes iron–wrapped around a panel of mica, a silicate mineral used as an insulator.
