Assertion(A): Photodiodes are preferably
used in the reverse bias condition for
measuring light intensity.
Reason(R): The fractional change due to the
photo-effects on the minority carrier
dominated reverse bias current is more easily
measurable than the fractional change in the
forward bias current.
used in the reverse bias condition for
measuring light intensity.
Reason(R): The fractional change due to the
photo-effects on the minority carrier
dominated reverse bias current is more easily
measurable than the fractional change in the
forward bias current.
View answer and explanation
Correct option: A
A and R are true and R is the correct
explanation of A
explanation of A
Option A is correct because photodiodes are used in reverse bias because the fractional change in the minority carrier current is more easily measurable.
