NEET Physics Question - Semiconductor Physics - P-N Junction Diode and its applications

Assertion (A): Width of depletion region is reduced in forward bias.

Reason (R): In forward bias external battery reduced the internal electric field in depletion layer.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

In forward bias, the external voltage opposes the built-in potential barrier, effectively reducing the internal electric field across the depletion region. This reduction in the electric field causes the depletion region to narrow. Hence, both Assertion (A) and Reason (R) are true, and (R) correctly explains (A).
