Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
Energy inputs refer to the energy that is supplied to a system or process, such as fuel, electricity, or raw materials that contain stored energy. Energy outputs are the energy that is produced or released as a result of that system or process, which can include useful work, heat, or light. The efficiency of a system is often determined by comparing its energy outputs to its energy inputs, highlighting how effectively energy is converted or utilized. Understanding these concepts is crucial in fields like engineering, environmental science, and economics.
Energy efficiency is typically calculated using the equation: Energy Efficiency = (Useful energy output / Energy input) * 100%. This formula helps to quantify how effectively an energy source is converted into useful outputs relative to the total input energy.
Material or energy that comes out of a system is typically referred to as an output. Outputs can include waste products, byproducts, heat, or useful products generated by a system as a result of its processes or operations. These outputs can have various impacts on the environment and surrounding systems.
In an electric heater, the useful energy is the heat generated for warming the room, while the wasted energy is the heat lost through the surroundings. In a television, the useful energy is the light and sound produced for viewing and listening, while wasted energy can come in the form of heat generated by the device. In an electric kettle, the useful energy is the heat used to boil water, while wasted energy can be heat lost through the kettle's exterior. In headphones, the useful energy is the sound produced for listening, while any energy lost through heat or vibration could be considered wasted.
usually on the side or at the back depending on what type of tv it is
Unless your Bose speakers have an optical digital input, no. There is no audio outputs or speaker outputs on this TV except for optical.
Recording must be done through the OUTPUTS of the TV.
If your TV has RCA audio outputs, you can connect an amplifier to these outputs to plug in speakers. If it has a headphone jack, you can connect computer-type amplified speakers to this output.
I assume you mean what it is converted to. It can be converted to many different types of energy; that's one of the things that makes electrical energy so useful. (The other useful feature is that it is relatively easy to transport.) For example, a heating device can convert electrical energy to heat; a speaker converts it to sound; a television set or a computer monitor converts it to light; etc.
