Question

When light increases, the reverse current in a photodiode
a.increases b) decreases
c.is unaffected d) none of these?

Answer 1

when light increases, the reverse current in a photodiode increase
A) Increases

Answer 2

According to the data mentioned in the question that,

When the light increases,the reverse current in a photodiode:

The correct answer of this question is option ,"a", increases.

Because,in a photodiode the electricity flow is directly converted into light.Heat generation like the old filament bulbs are not necessary for the light generation in the photodiodes.

That's why generated light and the electricity is directly proportional in a photodiode.
