Questions
The dominant mechanisms for motion of charge carriers is forward and reverse biased silicon P – N junctions are
a
Drift in forward bias, diffusion in reverse bias
b
Diffusion in forward bias, drift in reverse bias
c
Diffusion in both forward and reverse bias
d
Drift in both forward and reverse bias
detailed solution
Correct option is B
In forward biasing the diffusion current increases and drift current remains constant so not current is due to the diffusionIn reverse biasing diffusion becomes more difficult so net current (very small) is due to the driftTalk to our academic expert!
