Question

Reverse leakage current in a transistor _______

(a) is affected by light

(b) is not affected by light

(c) increases with a decrease in pressure

(d) decreases with increase in temperature

I had been asked this question during an interview.

Origin of the question is Photoelectric Transducers in portion Transducers of Electrical Measurements

Answer 1

Right choice is (a) is affected by light

For explanation I would say: The reverse leakage current in a transistor is directly proportional to the intensity of light. It increases with the increase in light intensity.
