Question

energy output ÷ energy input = energy efficiency
energy efficiency × 100 = energy efficiency%

energy output = 35 units
energy input = 100 units

what is the energy efficiency percentage?

100%
35%
1%

Explanation:

Step1: Calculate Energy Efficiency

First, use the formula \( \text{Energy Efficiency} = \frac{\text{Energy Output}}{\text{Energy Input}} \). Substitute the given values: \( \text{Energy Output} = 35 \) units and \( \text{Energy Input} = 100 \) units. So, \( \text{Energy Efficiency} = \frac{35}{100} = 0.35 \).

Step2: Calculate Energy Efficiency Percentage

Next, use the formula \( \text{Energy Efficiency}\% = \text{Energy Efficiency} \times 100 \). Substitute the value of Energy Efficiency from Step 1: \( 0.35 \times 100 = 35\% \).

Answer:

35%
