Efficiency = (Useful Work done)/(Total Work done).
This is usually expressed as a percentage.
Example:
For every 200KJ of energy released from coal in a power plant, only 60KJ is converted to electrical energy. Therefore, Efficiency = 60/200 =30%.

The ratio of useful work output to work input is a measure of?
Efficiency
What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
When discussing engines the ratio of output work to input work expressed as a percentage is called .?
The efficiency of the machine.
What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
Percentage of work in to work out?
I think it is efficiency.;)
What is efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
The ratio of useful work output to work input is a measure of?
Efficiency
What is a percentage of work in to work out?
efficiency
What is the percentage of energy used to do work called?
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
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.
How can convert efficiency to percent?
Work done = (force * distance)>Efficiency (%) = (Work done output / Work done input) * 100
How efficiency is calculated?
work it out
When discussing engines the ratio of output work to input work expressed as a percentage is called .?
The efficiency of the machine.
Formula for calculating efficiency of a power supply?
Efficiency = workout / workin * 100% how do I format this in the worksheet if the workout=KG what the work in will be?
