Question

Dark Current in photodiode

Answer 1

In physics and in electronic engineering, dark current is the relatively small electric currentthat flows through photosensitive devicessuch as a photomultiplier tube, photodiode, or charge-coupled device even when no photonsare entering the device; it consists of the charges generated in the detector when no outside radiation is entering the detector. It is referred to as reverse bias leakage currentin non-optical devices and is present in all diodes. Physically, dark current is due to the random generation of electrons and holeswithin the depletion region of the device.plss mark that answer as brainliest!!!!

Answer 2

In physics and in electric engineering task current is the relatively small electric current that flies through photosensitive devices such as a photomultiplier tube , photodiode or charged coupled device even when no photons are entering the device .
