Viva question answer for the experiment
Photo diode characteristics

physics photo diode characteristics viva question with answers

This light detector is a current-to-voltage converter. The FET input op-amp prevents the loading of the photodiode and the voltage at the output is proportional to the current in the photodiode. So long as the photodiode response to the light is linear, the output voltage is proportional to the light falling on the photodiode.
