Which graph shows the variation with current I of the potential difference V of a filament lamp?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

A[Graph A: V vs I, curve starts at origin and increases with increasing gradient (concave up).]

B[Graph B: V vs I, curve starts at origin and increases with decreasing gradient (concave down).]

C[Graph C: V vs I, curve starts at a positive V-intercept and increases with increasing gradient (concave up).]

D[Graph D: V vs I, curve starts at a positive V-intercept and increases with decreasing gradient (concave down).]

✓ Correct answer

A: [Graph A: V vs I, curve starts at origin and increases with increasing gradient (concave up).]
