Answer :

The energy efficiency of the system is 25%.

Step 1

To find the energy efficiency of the system, we first need to determine the ratio of the energy output to the energy input.

Given:

- Energy Output = 25 units

- Energy Input = 100 units

The energy efficiency (Efficiency) is calculated as the ratio of the energy output to the energy input:

Efficiency = Energy Output÷Energy Input

[tex]\[ \text{Efficiency} = \frac{25}{100} \]\[ \text{Efficiency} = 0.25 \][/tex]

Step 2

To express the energy efficiency as a percentage [tex](\( \text{Efficiency \%} \))[/tex], we multiply the efficiency by 100:

[tex]\[ \text{Efficiency \%} = \text{Efficiency} \times 100 \]\[ \text{Efficiency \%} = 0.25 \times 100 \]\[ \text{Efficiency \%} = 25 \% \][/tex]

So, the energy efficiency of the system is 25%.

Final answer:

The energy efficiency of the system is determined by dividing the energy output (25 units) by the energy input (100 units) and then multiplying the result by 100 to get a percentage, resulting in an energy efficiency of 25%.

Explanation:

Energy efficiency is a measurement of how well a system converts energy into useful work and is calculated by taking the ratio of useful energy output to total energy input. In the given question, the formula to calculate efficiency is simply the energy output (25 units) divided by the energy input (100 units). To express this efficiency as a percentage, you multiply the ratio by 100. Therefore, the energy efficiency of the system is:

Efficiency = (Energy Output / Energy Input) x 100%

Efficiency = (25 units / 100 units) x 100%

Efficiency = 0.25 x 100%

Efficiency = 25%

Thus, the energy efficiency of the system is 25 percent.
