1.	How much time on an average does the LDR take for it’s resistance to change when light is incident?(a) 8 to 12 ms(b) 12 min(c) 30 s(d) 354 hrThe question was posed to me in quiz.The question is from LDR Sensor in section Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» The CORRECT option is (a) 8 to 12 ms To explain I would say: 8 to 12ms is the correct value of the TIME that an average LDR takes for its resistance to CHANGE in response to the light incident on it. It also takes about a second APPROXIMATELY for the resistance to rise back up to its initial value when no light is incident.
