If the efficiency of a machine is to be high, what should be low __________?
Correct answer: B. Losses
- A. Input power
- B. Losses
- C. True component of power
- D. kWh consumed
- E. Ratio of output to input
Explanation
Efficiency is output power divided by input power, so reducing losses allows a larger fraction of the input to appear as useful output. High input power or energy consumption alone does not guarantee high efficiency.
