WebJan 14, 2024 · How does a LDR work in a circuit? LDRs (light-dependent resistors) are used to detect light levels, for example, in automatic security lights. in the dark and at low light levels, the resistance of an LDR is high and little current can flow through it. in bright light, the resistance of an LDR is low and more current can flow through it. ... WebThe resistance for the LDR changes with the change in the light the amount of light falls on it is inversely proportional to the resistance. for example when the room is dark the resistance is up to 2 Mega Ohms and when the room is bright then the resistance will be 5-6 Ohms.
