JEE Main 9 April 2024, Shift 2, Physics Q49

Question 49 of 90 in this shift, Physics question 19 of 30, Section A.

The II-VV characteristics of an electronic device shown in the figure. The device is :

The figure, in words

I vs V (volt) graph: in the forward (positive V) region current rises slightly; in the reverse (negative V) region current is small and nearly flat then drops sharply (breakdown) at a large negative voltage; the negative current axis is marked 5 (microampere).
