A photoresistor (also known as a light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity.
When a photoconductive material is connected as part of a circuit, it functions as a resistor whose resistance depends on the light intensity.In this context, the material is called a photoresistor (also called light-dependent resistor or photoconductor).

Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...

Look for a light therapy box that provides 10,000 lux of light exposure, turn it on within the first hour of waking up, and use it for 20 to 30 minutes. Dry air. Bye, bye moisture. Winter air is ...
