A silicon (PN) junction at a temperature of 20°C has a reverse saturation current of 10 pico Ampere. The reverse saturation current at 40°C for the same bias is approximately.
30 pA
40 pA
50 pA
60 pA
Correct answer is B
By increasing the temperature by 10°C, Io becomes double. So by increasing temperature by 20°C, Io becomes 4 times the initial value... and it is 40 PA.
