Which energy transformation occurs in a toaster?
A
chemical to electric
B
electric to heat
C
solar to chemical
D
heat to electrical
Explanation: 

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: -A toaster uses infrared radiation to heat a piece of bread (see How Thermoses Work for information on infrared radiation). When you put your bread in and see the coils glow red, the coils are producing infrared radiation. The radiation gently dries and chars the surface of the bread.

Detailed explanation-3: -Answer and Explanation: Electrical energy is converted into thermal energy and light energy inside a toaster. The electrical energy flows through metal conductors in the toaster that have high resistance to current flow.

Detailed explanation-4: -Toasters and Toaster Ovens Toasters, toaster ovens and similar small appliances use nichrome element wire to convert electrical energy into heat energy. In these appliances, the heat energy then transfers to the food by radiation and convection.

Detailed explanation-5: -A toaster transforms electrical energy into thermal energy.
