OBJECTIVE : |
|
| |
Plot characteristics of LDR, i.e. Distance (light intensity) V/S Resistance of LDR
Calculate resistance of LDR for different light intensity
Plot characteristics of Photo Diode (in reverse bias), i.e. Distance (light intensity) V/S reverse leakage current of Photo Diode
Plot characteristics of Photo Transistor, i.e. Distance (light intensity) V/S collector current of Photo Transistor
Plot output characteristics of Photo Transistor, i.e. VCE V/S IC for constant light intensity
