Question

If the temperature increases 10°C, the ratio of final reverse saturation current to initial reverse saturation current is _______

(a) 1

(b) 2

(c) 1.5

(d) 3

I got this question during an interview for a job.

My question is taken from Characteristic Equation of Diode-2 in portion Diode Circuit of Analog Circuits

Answer 1

The correct option is (b) 2

Explanation: The equation relating final reverse saturation current (Io2 ) to initial reverse saturation current (Io1 ) is given by

Io2 = 2^(∆T/10)Io1 Where ∆T is temperature change

Ratio will be 2^(∆T/10) = 2^1 = 2.
