The efficiency of the device for the given input and output energy is 40%.
The given parameters;
- input energy for the given device, = 100 J
- output energy for the given device, = 40 J
The efficiency of the device is defined as the ratio of out put energy to input energy of the given device.
[tex]Eff = \frac{0ut put}{1nput } \times 100\%[/tex]
Substitute the given parameters in the equation above and solve the for the efficiency.
[tex]Eff = \frac{40}{100} \times 100\% = 40\%[/tex]
Thus, the efficiency of the device for the given input and output energy is 40%.
