In series resistance ADDS UP!
In series, the total resistance is the sum of the resistors.
This means that two or more resistors in series is more effective than just one because the battery has to push the charges through two resistors.
The bigger the total resistance of a component the greater its share of total PD. This is because more work is done by the charge as it moves through a large resistance.
If the resistance of one component changes (LDR of thermistor) then the resistance of the other components changes too.
