To Measure light intensity we use
(A) LED with reverse bias
(B) photodiode with forward bias
(C) photodiode with reverse bias
(D) LED with forward bias

In which case is the junction diode is not reverse bias-

In the figure, which of the diode is in reverse bias

Why photodiodes are required to operate in reverse bias explain.

Reverse bias applied to a junction diode

For a reverse bias P-N junction-

Which of the following pn junction is not used in reverse bias?

Which one of the following represents forward bias diode?

The current in the forward bias is known to be more (in mA ) than the current in the reverse bias (in mu A ). What is the reason then to operate the photodiodes in reverse bias?

With reference to a semi-conductor diode, what is meant by: Forward bias

In a zener diode, break down occurs in reverse bias due to
