The trainer helps to study the following experiments :
- V - I characteristics of LDR at constant illumination.
- Current Vs. illumination characteristics at constant voltage.
- Illumination vs. Resistance characteristics and also for conductance characteristics.
- Spectral response characteristics of LDR.
The trainer contains :
- I.C. regulated variable power supply.
- One digital voltmeter & milliammeter.
- One digital Lux meter.
- Optical bench with graduated steel scale.
- Lamp holder assembly with stand.
- LDR holder with sliding stand fitted on to the optical bench.
- Set of colour filters & holder with stand.
