Product Description

This light-dependent resistor (LDR) unit demonstrates how the resistance of a photoconductor changes with light intensity. In darkness, resistance is high; in bright light, resistance decreases significantly. Suitable for physics and electronics experiments studying photoconductivity, light sensors, and the relationship between light and electrical resistance.
