Assertion:The dominant mechanism for motion of charge carriers in forward and reverse biased silicon `P-N` junction are drift in both forward and reverse biase. Reason: In reverse biasing, no current flow through the junction.A. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD. If both the assertion and reason are false. |

Answer» Correct Answer - D In `PN`-junction, the diffusion of majority carriers takes place when junction is forward biased and drifting of minority carriers takes place across the function, when reverse biased. The reverse biase opposes the majority carriers but makes the minority carriers to cross the `PN`-junction. thus the small current in `muA` flows during reverse biase. |
