A photoresistor (or light-dependent resistor, ldr, or photoconductivecell) is a light-controlled variable resistor the resistance of a photoresistor decreases with increasing incident light intensity in other words, it exhibits photoconductivity. The end of the bulb was always 10cm from the ldr method: 1 set up apparatus as shown: the bulb should be aligned so that it is clamped 0 1m directly above the ldr- this is difficult to represent on the diagram.
