Question

energy output ÷ energy input = energy efficiency
energy efficiency × 100 = energy efficiency%
energy output = 95 units
energy input = 100 units
what is the energy efficiency percentage?
100%
15%
95%

Explanation:

Step1: Calculate Energy Efficiency

Using the formula \( \text{Energy Efficiency} = \frac{\text{Energy Output}}{\text{Energy Input}} \), substitute the given values: Energy Output = 95 units, Energy Input = 100 units. So, \( \text{Energy Efficiency} = \frac{95}{100} = 0.95 \).

Step2: Calculate Energy Efficiency Percentage

Using the formula \( \text{Energy Efficiency}\% = \text{Energy Efficiency} \times 100 \), substitute the value of Energy Efficiency (0.95) from Step 1. So, \( \text{Energy Efficiency}\% = 0.95 \times 100 = 95\% \).

Answer:

95%
