Produced by forward biasing the photodiode
Produced by the random generation of electrons and holes in the depletion region
Produced by incident photons generating electrons and holes in the depletion region
Produced by reversed biasing the photodiode
The electric charge remains the same as the junction barrier is not affected
The electric charge flow is restricted due to the increased junction barrier
The electric charge flows freely due to the decreased junction barrier
