When n = energy efficiency and Pin = energy input and Pout = energy output, how can you mathematically represent the correct relationship between the energy you put in something and the energy you get out?
A. n = P out * P in
B. n = P out / P in
C. n = P out - P in ...?

Respuesta :

Energy efficiency computes the amount of input power converted into output power. Thus, n = Pin / Pout. Therefore, B.

Answer:

[tex]n=\frac{P_{out}}{P_{in}}[/tex]

Step-by-step explanation:

We know that,

[tex]\text{Energy efficiency}=\frac{\text{Energy out put}}{\text{Energy in put}}[/tex]

If [tex]P_{in}[/tex] represents the energy input,

[tex]P_{out}[/tex] represents the energy output,

And, n represents energy efficiency,

Hence, the required formula would be,

[tex]n=\frac{P_{out}}{P_{in}}[/tex]

i.e. OPTION B is correct.
