Explain an energy transformation you have observed in class.?

In class, I observed the transformation of electrical energy into light energy when we turned on a light bulb. The electrical energy from the power source is converted into light energy and heat energy by the filament inside the bulb, allowing us to see and illuminate our surroundings.


What is the energy transfer in a TV set?

In a TV set, electrical energy is transformed into light energy and sound energy. Electrical energy is used to power the screen to produce images and the speakers to produce sound. This transfer of energy allows us to see and hear the content displayed on the TV screen.


How electrical energy is converted into sound energy?

Electrical energy is converted into sound energy through a process involving an electrical signal passing through a transducer, such as a speaker or a buzzer. The electrical signal causes the transducer to vibrate, which in turn creates sound waves that we perceive as sound. This conversion process allows us to hear the audio produced by devices like speakers, headphones, and microphones.


What is the useful energy in a radio?

The useful energy in a radio is the electrical energy converted into radio waves that transmit sound through speakers, allowing us to listen to music or news.
