The efficiency of the machine which has an energy loss of 10% is 90%
What is efficiency?
This can be defined as the capacity to achieve a given task with little or no waste. Mathematically, it can be expressed as
Efficiency = (output / input) × 100
How to determine the efficiency
We shall assume the following:
- Input = 100 J
- Output = 100 – 10 = 90 J
- Efficiency =?
Efficiency = (output / input) × 100
Efficiency = (90 / 100) × 100
Efficiency = 90%
