Under which condition does a Light Dependent Resistor (LDR) decrease its resistance?

A Light Dependent Resistor (LDR) is a type of resistor whose resistance decreases as the light intensity increases. When exposed to bright light, the LDR allows more photons to strike its surface, which liberates more charge carriers within the material, resulting in a decrease in resistance.

This property makes LDRs useful in various applications, such as in light-sensitive circuits, automatic lighting systems, and photography, where they can respond to varying light conditions. In contrast, under low light conditions, the resistance remains high, as there are fewer photons interacting with the material. Thus, the expected behavior of an LDR is to lower its resistance when in bright light, confirming that this is the correct condition for the given question.
