With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: A semiconductor diode is a device typically made from a single p–n junction. At the junction of a p-type and an n-type semiconductor there forms a depletion region where current conduction is inhibited by the absence of mobile charge carriers. When the device is "forward biased" (connected with the p-side at higher electric potential than the n-side), this depletion region is diminished, allowing for significant conduction, while only very small current can be achieved when the diode is "reverse biased" and thus the depletion region expanded.
text_B: Is the current conduction negatively affected by the amount of mobile charge carriers?
YES.
