1. The problem statement, all variables and given/known data Why is sensitivity in a potential divider circuit greatest when the resistance of the fixed resistor is equal to the average resistance of the other resistor (in my case a LDR)? This isn't a homework question, but I need to include a bit on why I chose the fixed resistor I did in my coursework - I know I chose it for the reason that it has the highest sensitivity, but I need to explain why this is. 2. Relevant equations V2 = (R2 / (R1 + R2)) * V1 3. The attempt at a solution ...I don't know >.>; help much appreciated.
