JEE Main 30 July 2022, Shift 2, Physics Q18

Question 18 of 90 in this shift, Physics question 18 of 30, Section A.

[figure: I-V graph] The I-V characteristics given in above figure is related to:

The figure, in words

I (mA) on vertical axis, V (volt) on horizontal axis, origin marked 0. A single curve lies in the fourth quadrant, starting at a point on the positive V axis and curving down-left to a point on the negative I axis (ending at a dot on the I axis below the origin).
