A pn junction is forward biased when
A) the applied potential causes the n-type material to be more positive than the p-type material.
B) the applied potential causes the n-type material to be more negative than the p-type material.
C) both materials are at the same potential.
D) Both A and C above.

Question

Quizplus · Accepted Answer

When a pn junction is forward biased, the applied potential makes the n-type material more negative relative to the p-type material. This reduces the barrier for charge carriers to move across the junction, allowing current to flow.
