An air conditioner uses 10,832 J of energy to run, but only 5,488 J of energy is used to heat or cool the air of a home. What is its energy efficiency?

Answer :

The input energy of the air conditioner is

[tex]E_{i\text{ n}}=10832\text{ J}[/tex]

The output energy of the air conditioner is

[tex]E_{out}=5488\text{ J}[/tex]

The formula to calculate efficiency is

[tex]\eta=\frac{E_{out}}{E_{i\text{n}}}\times100\text{ percentage}[/tex]

Substituting the values, the efficiency will be

[tex]\begin{gathered} \eta=\frac{5488}{10832}\times100\text{ percentage} \\ =50.66\text{ percentage.} \end{gathered}[/tex]

Thus the energy efficiency is 50.66%.
