Energy Output = 25 units

Energy Input = 100 units

What is the energy efficiency of the system?

$
25 \div 100 = 0.25
$

$
0.25 \times 100 = 25\%
$

Energy Efficiency [tex]$=$[/tex] 25\%



Answer :

To determine the energy efficiency of the system, follow these steps:

1. Identify the given values:
- Energy Output: 25 units
- Energy Input: 100 units

2. Calculate the energy efficiency:
The energy efficiency can be found using the formula:
[tex]\[ \text{Energy Efficiency} = \frac{\text{Energy Output}}{\text{Energy Input}} \][/tex]
By substituting the given values:
[tex]\[ \text{Energy Efficiency} = \frac{25}{100} = 0.25 \][/tex]

3. Convert the energy efficiency to a percentage:
To express the efficiency as a percentage, multiply the energy efficiency by 100:
[tex]\[ \text{Energy Efficiency Percentage} = 0.25 \times 100 = 25.0\% \][/tex]

Thus, the energy efficiency of the system is 0.25 (or 25.0%).
