Sample questions

Question 1

Consider the following statements regarding a p-n junction diode: 1. In forward bias, the depletion region width decreases. 2. In reverse bias, the depletion region width increases. 3. The current flows due to majority carriers in both forward and reverse bias. 4. Zener diode is designed to operate in the reverse breakdown region. Which of the above statements are correct?

Question 2

A graph shows the current-voltage (I-V) characteristics of two different semiconductor devices: Device X and Device Y. Device X shows a small current for positive voltage and then a sharp increase, whereas Device Y shows a small current in one direction and a much larger current in the opposite direction only after a certain threshold. Which of the following is correct?

Question 3

For the given combination of gates, if the logic states of inputs A, B, C are as follows A = B = C = 0 and A = B = 1, C = 0 then the logic states of output D are
