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?
15%
95%
100%

Explanation:

Step1: Calculate energy efficiency

Energy efficiency = Energy output ÷ Energy input
Energy efficiency = \( \frac{95}{100}=0.95 \)

Step2: Calculate energy efficiency percentage

Energy efficiency percentage = Energy efficiency × 100
Energy efficiency percentage = \( 0.95\times100 = 95\% \)

Answer:

95%
