The LDR Characteristics Apparatus is a physics and electronics laboratory apparatus used for studying how the resistance of a light dependent resistor changes with illumination. It is designed for school physics labs, college practical rooms, STEM classrooms, and electronics demonstrations where students observe light-controlled resistance behaviour.

Product Description

The LDR Characteristics Apparatus by School Equipments helps students investigate the relationship between light intensity and LDR resistance. It supports practical learning of photoresistance, sensor response, potential divider circuits, and basic light-sensing electronics.

This apparatus is suitable for teacher demonstrations and student practicals in current electricity and electronics. The final supplied configuration may include an LDR sensor, lamp or light source, meter connections, resistance measurement arrangement, variable distance setup, and connecting leads. Exact range, light source rating, sensor type, and included accessories should be confirmed before publishing.
