Therefore, V=β i2 (Parabolic curve) where β is the constant.

Q. Suppose the drift velocity $v_{d}$ in a material varied with the applied electric field $E$ as $v_{d} \propto E .$ Then $V - I$ graph for a wire made of such a material is best given by :

$i = n e A v_{2} = n e A (k E)$ , where $k$ is the constant
$i = n e A k \frac{V}{d}$ , where $V$ is the potential difference and $d$ is the length of the conductor.
Therefore, $V = β i^{2}$ (Parabolic curve)
where $β$ is the constant.

Q. Suppose the drift velocity vd​ in a material varied with the applied electric field E as vd​∝E​. Then V−I graph for a wire made of such a material is best given by :

i=neAv2​=neA(kE​), where k is the constant i=neAkdV​​, where V is the potential difference and d is the length of the conductor. Therefore, V=βi2 (Parabolic curve) where β is the constant.

Q. Suppose the drift velocity $v_{d}$ in a material varied with the applied electric field $E$ as $v_{d} \propto E .$ Then $V - I$ graph for a wire made of such a material is best given by :

$i = n e A v_{2} = n e A (k E)$ , where $k$ is the constant
$i = n e A k \frac{V}{d}$ , where $V$ is the potential difference and $d$ is the length of the conductor.
Therefore, $V = β i^{2}$ (Parabolic curve)
where $β$ is the constant.
