Which of the following forms of energy is used to run electrical appliances?

When you turn on a device that is battery-operated, such as a flashlight or a toy, the electrical potential energy stored in the battery is converted into other forms of energy such as sound, mechanical motion, thermal energy, and light.

What form of energy is used to run electrical appliances?

The common forms of energy used in our houses are electrical energy, chemical energy available from fuels, food and energy originating from the sun. Electrical energy is transformed into many forms – mechanical/kinetic, sound, heat, light, and other forms of electromagnetic radiation – by everyday appliances.

What are the 4 types of electrical energy?
