Answer:

The electrical toaster oven and electrical fan are commonly used household appliances that include the conversion of energy from electrical to heat energy.

The toaster oven is used to toast the slices of bread and it warms the food releasing heat energy by the use of electrical energy.

Due to this rotating blades again there occurs another type of energy in the fan's motor known as the heat energy as the blades are connected to the motor.
