A) a p-n junction
B) an intrinsic semiconductor
C) a p-type semiconductor
D) an n-type semiconductor
Correct Answer: A
Solution :When the connection of battery is reversed, then a semiconducting device is reverse biased. We know that in forward biasing of \[p-n\] junction the current is of the order of milliampere while in reverse biasing the current is of the order of microampere (negligible). Thus, device is a \[p-n\] junction.
