When the n-side of a diode is positive and the p-side negative, the diode is:

1. This is the opposite connection to forward bias. 2. The applied voltage now adds to the barrier potential. 3. When n-side is positive and p-side is negative, it is said to be reverse biased. 4. So the answer is reverse biased. _Source: syllabus Physics Part II, Ch 14 'Semiconductor Electronics'_
