the energy to wake up and get out of bed and put in the bread into the toaster and switch it on. then the energy to take the toast out before your house burns down. in other words, heat energy(specifically radiation if you are using a toaster) and electrical energy
The inside of a toaster includes electrical energy (what runs the toaster), radiant/light energy (the light coming off of the coils), and thermal/heat energy (what cooks the food in the toaster).
The change in energy in a toaster is usually in the form of electrical energy being converted to heat energy by the heating elements inside the toaster. This heat energy is then used to toast the bread or other foods placed inside the toaster.
When a toaster is turned on, electrical energy is converted into thermal energy, which is then used to heat up the toaster coils. The thermal energy produced toasts the bread placed inside the toaster.
Alternating current electrical energy.
A toaster is used in the same room as any other cooking appliance; in the kitchen. It is most recommended to use it for browning/toasting a slice of bread or a waffle for breakfast in the morning.
The researcher likely used a device called an energy meter or wattmeter to measure the electrical energy entering the toaster. This device measures the power consumption of the toaster over a period of time, which can then be used to calculate the total energy consumption. The unit of electrical energy is typically measured in kilowatt-hours (kWh).
When a toaster is unplugged, it no longer uses electrical energy from the wall outlet. However, the toaster may still have residual heat energy stored in its components for a short period of time after being unplugged.

A toaster converts electrical energy into thermal energy and radiant energy. The electrical energy is used to heat up the toaster coils, which then radiate heat to toast the bread.
To calculate the energy used by a toaster, you need to know its power rating. Let's assume a typical toaster uses around 800 watts. In 5 minutes, the toaster would consume 800 watts * 5 minutes = 4000 watt-minutes of energy. To convert to watt-hours, divide by 60 to get 4000 watt-minutes / 60 = 66.67 watt-hours, or 0.067 kilowatt-hours.
When you turn on a toaster oven, electrical energy from the outlet is converted into heat energy by the heating elements inside the oven. This heat energy is then used to cook or bake food placed inside the oven.
