Why does potential difference across a LDR with changes its resistance?

The resistance of a Light Dependent Resistor (LDR) changes due to its sensitivity to light intensity. When light falls on the LDR, photons excite electrons, reducing the resistance as more charge carriers become available for conduction. Consequently, as the light intensity increases, the potential difference across the LDR decreases, as it allows more current to flow for a given voltage. Thus, the potential difference varies inversely with the resistance of the LDR under changing light conditions.
