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.
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
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.
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.
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.
both are human sciences.
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.
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
Output is always greater than input. The output is multiplied from input.
The energy input is always greater than energy output.
Input energy = output energy + losses
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
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
Efficiency = ( useful energy output / total energy input ) x 100
Efficiency is output power divide by input power.
