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?

An = P out * P in
Bn = P out / P in
Cn = P out - P in ...?

Verified Answer :

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

Answer:

\(n=\frac{P_{out}}{P_{in}}\)

Step-by-step explanation:

We know that,

\(\text{Energy efficiency}=\frac{\text{Energy out put}}{\text{Energy in put}}\)

If \(P_{in}\) represents the energy input,

\(P_{out}\) represents the energy output,

And, n represents energy efficiency,

Hence, the required formula would be,

\(n=\frac{P_{out}}{P_{in}}\)

i.e. OPTION B is correct.
