Maximising the output of something whilst simultaneously minimising input.
Efficiency is: 100% x (the energy that goes to the intended task)/(total energy needed)
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
The ratio of output to input of a system or process.
Output work divided by input work
ampere hour unit of battery
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
It uses a HEPA filter
The ratio of the effective output to the total input in any system.
cost efficiency is how good what you paid for was for the price you paid for it. it pretty much rates the quality and the price as a comparison in one.
hydrogen nuclei join together to make a larger helium.
The ability to create value through control, innovation and efficiency.
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
