No bias is applied to a - junction, then the current
View answer and explanation
Correct option: B
Is zero because the charge carriers do not move
Option D (None of these) is incorrect and the correct answer is that the current is approximately zero due to the depletion region, but there is a very small current due to thermally generated carriers. Since none of the options perfectly describe this, the closest is that the current is approximately zero because the charge carriers do not move freely due to the depletion region.
