Q1:

Assertion (A): A decrease in temperature increases the reverse saturation current in a p-n diode. Reason (R): When a diode is reverse biased surface leakage current flows.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not a correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:D - A is false but R is true

A is wrong because decrease in junction temperature decreases reverse saturation current.
