A photo-resister is already a resister and will limit the voltage in the circuit. Why can't this be connected to a pin and measured? Why is a second resister needed to connect the photo-resister to ground.

Thank you

A photo-resistor or potentiometer is already a resistor and will limit the voltage in the circuit. Why can't this be measured? Why do you need a second resistor to setup a voltage divider to measure the divided voltage?

Thank you
