Why do these two ways to calculate the resistance at a given temperature give different answ...
When I use the linear equation, I have always written it as $R_{2}=R_{1}(1+\alpha \ \Delta T)$.
For this problem, $R_{1}=100\Omega$ and $R_{2}=200\Omega$. Also substituting the value for $\alpha$ wil …

Potentiometer voltage change
The potentiometer is not a normal resistor. They are often used simply as variable resistors, but in this example its use does its name justice -- "potentiometer" = voltage measure. The float is attac …
