Here's how it works:
* Radio waves: Radio stations transmit radio waves, which are a type of electromagnetic radiation.
* Antenna: The radio's antenna captures these radio waves.
* Electrical signals: The antenna converts the radio waves into electrical signals.
* Decoder: The radio's circuitry decodes these signals, extracting the audio information.
* Speaker: Finally, the speaker converts the electrical signals back into sound waves that you can hear.
So, a radio doesn't release electrical energy. It uses electrical energy to create sound energy.
