LIGHT DEPENDING RESISTOR
Light Depending Resistor (LDR) is a light-
It is made from cadmium sulfide (CdS).
sensitive transducer, which converts light
energy into electrical energy and also know
as a Photo Resistor.
It is a variable resistor whose value decreases
with increasing incident light intensity.
The resistance decreases as the brightness of light
falling on the LDR increases.
It is made from cadmium sulfide (CdS).
