The amount of current through the resistor depends on the number of free carriers, which is in turn dependent upon the intensity of the light. So, in short, the amount of light on the resistor ...

The hybrid street light is available in 20 W, 40 W, and 60 W versions. “The light-dependent resistor (LDR) in the street light enables an automatic switch on/off.

Spectrophotometry is an important scientific tool, most commonly used in biology and chemistry. It’s a method to measure the amount of light absorbed by a chemical solution at various differe… ...

A new study demonstrates how light-dependent resistors (LDRs) and waveguides enable affordable, real-time optical detection in microfluidic Lab-on-a-Disc platforms for diagnostics and fluid tracking.
