The dominant mechanisms for motion of charge carriers in forward and reverse biased silicon `P-N` junction are

drift in forward bias, diffusion in reverse bias

diffusion in forward bias, drift in reverse bias

diffusion in both forward and reverse bias

drift in both forward and reverse bias

Text Solution

Verified by Experts

The correct Answer is:

In p-n junction, the diffusion of majority carriers takes place when junction is forward biased and drifting of minority carriers takes place across the junction, when it is reverse biased.

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.

If both the assertion and reason are true and reason is a true explantion of the assertion.

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

If the assertion is true but reason false

If both the assertion and reason are false.

The dominant mechanisms for motion of charge carriers in forward and reverse biased silicon P-N juntions are-

Drift in forward bias, diffusion in reversebias

Diffusion in forward bias, drift in reverse bias

Diffusion in both forward and reverse bias

Drift in both forward and reverse bias

Assertion : The dominant mechanism for motion of charge carreis in forward and reverse biased silicon P-N junction are drit in both forward and reverse bias. Reaon : In reverse biasing, no current flow through the junction.
