: Suppose you’re trying to measure an unknown sensor resistance, o , by converting it to a voltage. For a fixed set of values of 1 ,1 , and , each of the following circuits will yield an output voltage, o , as function of o . a. [10 points] For each of these circuits, write the equations relating o to o . b. [10 points] Find the sensitivity for each of these circuits (note that the sensitivities for some of these circuits may not be constants).

(a) R₁ / (R₁ + )

(b) - / (R₁ + )

Explanation:

(a)

i - Using voltage division rule =

v₀ = v₁ [ / (R₁+)]

The sensitivity is

ii - = dv₀/d  *  /v₀

                = R₁ / (R₁ + )

(b)

i - Using voltage divisor rule = v₀ = v₁ [ / (R₁+)]

ii - =  dv₀/d  *  /v₀

               = - / (R₁ + )

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
