A radio primarily uses electrical energy to power its components such as the circuitry, speakers, and display. The electrical energy is converted into electromagnetic energy in the form of radio waves, which are then transmitted through the air to be received by the radio's antenna. The radio then converts these radio waves back into electrical signals that can be amplified and converted into sound waves for us to hear.
