Question

1.Name the type of biasing of a p-n type junction diode so that the junction offers a very high resistance. 2.Name two factors on which the electrical conductivity of a pure semiconductor at a given temperature depends. 3. Identify the logic gates marked x and y in the following figure. Write down the output as when A = 1 , B = 1 and A = 0 and B = 0

Answer 1

1st . Reverse biased p-n junction offers infinite resistance.
