Question

Suppose the drift velocity v d in a material varied with the applied electric field E as v d ∝ E . Then V - I graph for a wire made of such a material is best given by:, , , ,

MARKS App · Accepted Answer

We know that v d = k E and I = n e A v d , ⇒ I = n e A k E ∵ E = V d ⇒ I = n e A k V d ⇒ I ∝ V ⇒ V ∝ I 2 . So,
