Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.

How does a light bulb make heat?
The electrical energy input which is meant to turn the lights on is not 100% used (since no machine is 100% efficient.) Most of this energy is wasted as heat energy.If a substance reaches a certain temperature it gives off light and heat. When a filament light bulb reaches that temperature, it gives off both light and heat
What does production theory help us understand?
Production theory helps us understand how firms make decisions regarding the combination of inputs to produce goods and services efficiently. It helps in analyzing factors that influence production, such as technology, resource availability, and costs. Additionally, production theory is important for understanding how changes in input quantities and technology impact output levels and firm profitability.
What is an exogenous processes?
An exogenous process is a factor or variable that originates from outside the system being studied. In other words, it is a driver or input that influences the system but is not influenced by the system itself. Exogenous processes are important to consider in various fields such as economics, biology, and social sciences to understand the impact of external factors on the system under investigation.
The fundamental elements of computer?
The fundamental elements of a computer include the central processing unit (CPU), memory (RAM), storage (hard drive or SSD), input devices (keyboard, mouse), output devices (monitor, printer), and the motherboard which connects and controls these components. These elements work together to process data and execute tasks.
What is comparison between political science to other social sciences?
both are human sciences.
A comparsion of energy output with energy input?
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
What is a comparison of a machines work input and work output?
mechanical efficiency
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
What does efficiency compare energy output with?
Efficiency compares the useful energy output of a system to the total energy input. It provides a measure of how well a system converts input energy into useful output energy.
Why is input energy more useful than output energy?
Input energy is typically more useful than output energy because input energy is the initial energy put into a system to produce the desired output. Output energy, on the other hand, is the energy produced by the system after losses and inefficiencies have occurred, so it is usually less than the input energy. By maximizing input energy efficiency, we can achieve a more effective output.
What is the comparison between output and input work called?
The comparison between output and input work is called efficiency. It is a measure of how well a system can convert input work into useful output work. Efficiency is usually expressed as a percentage, with 100% being perfect efficiency.
The comparison between output work imput work is?
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
What is the term for the comparison of input and output work of a machine?
The term for the comparison of input and output work of a machine is efficiency. It is typically calculated as the ratio of output work to input work, expressed as a percentage. A higher efficiency indicates that the machine is better at converting input work into useful output work.
What is a comparison of a machines work output and work input?
mechanical efficiency
Efficiency is a comparison of?
Efficiency is output power divide by input power.
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
