really????? in the case of mains AC power, 1) power is (internally) converted to DC, in order to power the electronics --- still electrical energy. 2) an input signal is decoded and transformed into a/v signals --- still electrical in nature.???

∙ 12y agoIn a TV electrical energy is converted primarily into sound and light energies but also heat as a by product of the first two transformations.

∙ 12y agoA television receiver uses electrical energy, either from batteries or from the
electrical outlet it's plugged into, and converts that energy into a tiny bit of light
energy, a moderate amount of sound energy, and a considerable amount of
heat energy.

What kind of energy transformation does a game controller?
Mechanical when you press the controls to electrical when it transmits the control to the TV
What energy transfers take place when you watch TV?
The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.
What are examples of useful energy?
tv light bulb
Gasoline is an example of energy released by blank changes?
The coubustion of gasoline is an example of energy released by chemical changes
What are the kinds of energy and its example?
light energy: sun heat energy: fire, heater kinetic energy: moving cars mechanical energy: television potential energy: a compressed spring sound energy: thunder chemical energy: battery nuclear energy: nuclear submarines thermal energy:a piece of paper moving over a candle
What kind of energy does a television use?
A television uses electrical energy and changes into sound energy.
How does the energy change in a TV?
i don't know that's what i am trying 2 find out >:(
What makes the tv work?
electro magnetic waves that turn into sound energy and changes info
What is the definition of energy transformations?
2. Energy can change from one form to another. This is called an energy conversion or energy transformation. • The Law of Conservation of Energy states that energy can change form, but it cannot be created or destroyed. Therefore, the total amount of energy stays the same. • In energy transformations, some energy is always lost to the environment as thermal energy. Examples of energy transformations and their uses: · A television changes electrical energy into sound and light energy. · A toaster changes electrical energy into thermal energy and light. · A car changes chemical energy from fuel into thermal energy and mechanical energy. · A flashlight changes chemical energy from batteries into light energy. · Solar energy is converted into electrical energy using solar panels. · Campfires convert chemical energy stored in wood into thermal energy, which is useful for cooking food and staying warm.
What device changes electrical energy into light and sound energy?
A TeleVision because to produce an image, it needs to have some light shining from the back of the screen, therefore emitting light and it has speakers on it to produce sound all from electricity.
What are examples of mechanical energy being transformed into electrical or heat energy?
Any device or process that needs batteries or that needs to be "plugged in" to move is an example of electrical energy being converted into mechanical energy. Some examples: - Starting a car - Running a washer/dryer - A moving fan - Playing a record or CD
What is an example of energy transform?
candle ,light bulb ,television ,etc.its when say electrical energy goes through a toaster and turns into thermal energy or heat then sound when the toast is doneA energy can be changed or transformed. When you rub your hands together,your hands become warm. Mechanical energy due to motion is changed into heatenergyEnergy transformation is when a form of energy changes into another.by Chemical energyEnergy....comes from the sun and is practically used for everything!:)an energy transformation is when Engergy can be tranformed or transferred.energy is always transformed from one form to another.example:-the energy transformation of a television...Electrical energy-->light energy-->sound energyit's the process of changing energy frm one form to another one .
What changes chemical energy to energy?
The mitochondria changes food energy to chemical energy.
What changes mechanical energy to energy?
A generator changes mechanical energy into electrical energy.
