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

Step-by-step explanation:

We know that,

If represents the energy input,

represents the energy output,

And, n represents energy efficiency,

Hence, the required formula would be,

i.e. OPTION B is correct.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices
