The Light Dependent Resistor
As its name implies, the Light Dependent Resistor (LDR) is made from a piece of exposed semiconductor material such as cadmium sulphide that changes its electrical resistance from several thousand Ohms in the dark to only a few hundred Ohms when light falls upon it by creating hole-electron pairs in the material.
The net effect is an improvement in its conductivity with a decrease in resistance for an increase in illumination. Also, photoresistive cells have a long response time requiring many seconds to respond to a change in the light intensity.

A regular transistor is an electrical component that limits the flow of current by a certain amount dependent on current applied to itself through another pin - so there is the collector, emitter, and 'base', which controls how much current can pass through the collector through to the emitter.View More
