Assertion (A): When a high reverse voltage is applied to a p-n junction the diode breaks down.
Reason (R): High reverse voltage causes Avalanche effect.
Both A and R are true and R is correct explanation of A
Both A and R are true but R is not a correct explanation of A
A is true but R is false
A is false but R is true
Correct answer is A
Avalanche breakdown occurs at high reverse voltage.
As compared to an ordinary semiconductor diode, a Schottky diode
has lower cut in voltage
has higher cut in voltage
lower reverse saturation current
both (b) and (c)
Correct answer is A
Cut in voltage in Schottky diode is about 0.3 V as compared to 0.7 V in ordinary semiconductor diode.
Recombination produces new electron-hole pairs
True
False
Cannot say
It depends
Correct answer is B
Due to recombination, the number of electron-hole pairs is reduced.
In a bipolar transistor, the barrier potential is
0
a total of 0.7 V
0.7 V across each depletion layer
0.35 V
Correct answer is C
Since there are two p-n junctions, there are two depletion layers and 0.7 V across each layer.
