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?
35%
100%
1%

Explanation:

Step1: Calculate energy efficiency

Energy efficiency = Energy Output / Energy Input.
So, energy efficiency = \( \frac{35}{100}=0.35 \).

Step2: Calculate energy efficiency percentage

Energy efficiency percentage = Energy efficiency × 100.
So, energy efficiency percentage = \( 0.35\times100 = 35\% \).

Answer:

35%
