LDR Characteristics Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11203
An LDR, or light-dependent resistor, is a photosensitive component whose resistance normally decreases as the illumination falling on its active surface increases. This apparatus enables students to observe that response, take electrical measurements and plot the characteristic relationship between illumination and resistance or current.
The LDR Characteristics Apparatus supports structured classroom demonstrations and student practical work. Product-specific construction, meter arrangement, illumination source, operating voltage and measurement ranges must be confirmed against the final supplied model before procurement or publication.

Frequently Asked Questions
What is an LDR Characteristics Apparatus used for?
It is used to study how the resistance or current response of a light-dependent resistor changes when the illumination falling on it changes.
What happens to an LDR when light intensity increases?
The resistance of a typical LDR decreases as incident light intensity increases. The exact response depends on the sensor and experimental conditions.
Can students plot a characteristic graph with this apparatus?
Yes. Students can record readings at different light levels and plot resistance, current or another specified electrical parameter against illumination.
Is the apparatus suitable for school laboratories?
Yes. It is suitable for supervised physics and introductory electronics experiments where LDR and light-sensor behaviour are included in the practical work.
Does the apparatus include built-in meters?
The meter configuration has not been verified. Confirm whether the selected model includes built-in meters or requires external laboratory meters.
What should a buyer confirm before ordering?
Confirm the operating voltage, LDR type, illumination source, meter ranges, included leads, dimensions, accessories and experiment manual.
