Statement-I: The dominant mechanism for motion of charge carriers in forward and reverse biased silicon junction are drift in both forward and reverse bias.
Statement-II: In reverse biasing, no current flow through the junction.
Statement-II: In reverse biasing, no current flow through the junction.
View answer and explanation
Correct option: D
If both statements are incorrect.
Option D (If both statements are incorrect) is correct because in forward bias, diffusion dominates, and in reverse bias, drift dominates, and a small current *does* flow in reverse bias due to minority carriers.
