Q. The actual operation of a phototransistor depends on the biasing arrangement and__

A
Light frequency
B
electrical energy
C
reverse bias
D
None of these
Solution:

The actual operation of a phototransistor depends on the biasing arrangement and light frequency. … On the other hand, if the same junction is reverse biased, the increase in current flow will be considerable and is a function of the light intensity. Therefore, reverse bias is the normal mode of operation.
