Answer:
To study the effect of intensity of light (by varying distance of the source) on a LDR (Light Dependent Resistor). ... Light dependent resistor or a photoresistor is a device that is sensitive to light. Its resistance varies according to the intensity of light incident on it.

Answer:
Its resistance depends upon the intensity and duration of light incident on it. A good quality LDR shows a resistance variation from 1 MΩ in complete darkness to about 10 Ω in full day light. The intensity of light decreases inversely with increase the square of distance.
