What is the energy transformation in a radio?

Answer 1

A radio receiver converts electrical energy into heat and sound energy.

The electrical energy comes from the batteries in the radio or the wall-outlet that it's

plugged into. The tiny tiny tiny bit of electrical energy from the current in the antenna

that's caused by the radio waves that hit it is used to control the real energy in the

radio, but doesn't directly add anything to it.

If you've ever used a boy-scout "crystal set" radio, and remember how soft the sound

is in the earphones, that's how much energy is actually drawn from the radio waves.

Not much !

Answer 2

The energy transfers lost in the radio are sound and heat, i think the other transfers going into the radio is heat and kinetic energy. x

Answer 3

first it goes throgh the stage of chemical>electrical>acoustic

Answer 4

Electric (from the wall) to sound (speakers).
