Efficiency, defined as the ratio of useful output to total input, cannot exceed 100 percent under normal circumstances, as this would imply that more output is produced than the input supplied. However, in certain contexts, such as in the case of regenerative processes or systems that harness energy from external sources, it might seem like efficiency exceeds 100 percent. This is often a misinterpretation, as it may involve additional energy or resources not accounted for in the original input. Therefore, while it can appear that efficiency exceeds 100 percent, it does not adhere to the conventional definition.

why is the efficiency of a calorimeter less than 100%


What is the efficiency is the output work is 12000 and the input work is 15000?

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%.


Can a machine have 110 percent efficiency?

Nothing can be more that 100% (one hundred percent)! When people say that something is one hundred and ten percent - they are wrong. It is an attempt to imply that something is greater that it should be. It is similar to the annoying habit of adding !!!! at the end of a sentence, when a single ! is correct.

If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?

No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.

The efficiency of an actual machine is always less than what percent?

It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!

Can a machine's efficiency can be greater than 100 percent?

nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.


Why is efficiency of machine not 100?

If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?
