Resistance and Resistivity
 

Resistance and Resistivity problem 39


A car has sensors for detecting the light intensity and temperature of its environment. The sensors make use of a light-dependent resistor (LDR) and a thermistor. The car moves from a warm and dark environment into a cold and bright environment. What are the changes to the resistances of the LDR and thermistor?
