1. Microphone : Converts sound energy
(our voice) into electrical energy.
2. Headphones : The batteries of the device (to which the headphone is plugged) use chemical potential energy to make electricity which is in turn converted into sound energy by the headphones.
3. Solar Cell : Converts sunlight directly into electricity, via the photovoltaic effect.
4. Photoelectric Cell : Experiences Photovoltaic effect — electrical charge is generated, when exposed to light.
5. Electric Cell : the chemical energy is itransformed to electrical energy.
