What occurs when a radio is plugged into an outlet and turned on?

When a radio is plugged into an outlet and turned on, electrical current flows from the outlet through the radio's power cord. This current powers the internal components, allowing the radio to receive signals from radio waves transmitted through the air. The radio then processes these signals, converting them into sound that can be heard through the speakers. Additionally, various controls on the radio allow users to adjust volume, frequency, and other settings.
