Question

energy efficiency
energy output = 25 units
energy input = 100 units
energy efficiency = 0.25
now, if you want to calculate energy efficiency percentage, what value should be substituted into the green box?
? × 100 = energy efficiency %
energy efficiency × 100 = energy efficiency %
hint: enter a number.

Explanation:

Step1: Identify the formula component

The formula for energy efficiency percentage is given as \([?] \times 100=\text{Energy Efficiency}\%\), and we know that \(\text{Energy Efficiency} \times 100=\text{Energy Efficiency}\%\). So the value to substitute in the green box (the \([?]\)) is the energy efficiency value.

Step2: Use the given energy efficiency

We are given that Energy Efficiency \( = 0.25\). So this is the value that should be substituted.

Answer:

0.25
