Study the photoconductivity of CdS photoresistor.

Optical bench makes precise optical alignment easy
Easy light intensity adjustment via two polarizers
Simple, color-coded electrical connections

The phenomenon of photoconductivity occurs when an incident light shown upon a semiconductor causes an increase in its electrical conductivity. This is because of the excitation of electrons across the energy gap into the conduction band, which leads to an increase in the number of free carriers in the conduction band, hence, an increase in the conductivity of the semiconductor. Here, we can study the characteristics of the CdS photoresistor under different conditions of light intensity and applied voltage.

Ordering information: Kit includes optical bench set 0.4 m, light source holder, polarizer holder, analyzer holder, LDR module holder, power supply, 0 to 15 V, 200 mA, power supply for light source, instruction manual.
