IB Physics SL A.3.13 Efficiency
Improve efficiency calculations by connecting useful output to total input and using power or energy data from realistic devices.
How this is tested
- use efficiency = useful output/input to find a missing power, energy, height, or fuel mass
- for panels or turbines, combine efficiency with area, intensity, or speed before comparing output
- state wasted energy clearly and keep power or energy units consistent when quoting efficiency
