Efficiency as a percent is output/input * 100%
12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.

How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
The ratio of output compaired to in input?
It is the efficiency of a machine.
The ratio of output work to input work is?
efficiency
Efficiency can be express mathematically as?
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.
What is the efficiency of a car's engine when he input is 20000 joules and the waste heat is 15000 joules?
The efficiency of the car's engine is calculated by dividing the useful energy output by the energy input. In this case, the useful energy output would be 5000 joules (20000 input - 15000 waste heat), thus the efficiency would be 5000/20000 = 0.25 or 25%.
What is the efficiency of a device that takes in 40000 J of heat and does 12000 J of work while giving off 28000 J of heat?
Efficiency is calculated as the ratio of useful work output to the total heat input. In this case, the useful work output is 12000 J, and the total heat input is 40000 J + 28000 J = 68000 J. The efficiency would be (12000 J / 68000 J) * 100% = 17.65%.
What is the formula to finding the work output of efficiency?
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
What means work output divided by work input?
Work output divided by work input is known as the efficiency of a system. It represents the ratio of useful work output compared to the total work input required to perform a task. A system with high efficiency is able to convert a larger portion of input energy into useful output energy.
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
What is the ratio of output to input?
efficiency
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.
Which math ratio represents efficiency?
Efficiency = Output/Input.
Which shows relationship between work input and work output?
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
How do you find output force if you are only given efficiency and work?
You can find the output force by dividing the work done by the input force by the efficiency. This formula is: Output Force = Work / (Input Force * Efficiency).
What compares the energy output of a system with its energy input?
Energy efficiency compares the energy output of a system to its energy input. It indicates how much of the input energy is converted into useful output energy, with higher efficiency values indicating less energy wasted.
