\text { Consider the relation } E=\frac{i R}{\rho}=\frac{i \rho}{A}

\text { As } \mathrm{i}=\mathrm{neAv}_{\mathrm{d}}

\text { Therefore, } \mathrm{E}=\mathrm{n}_{\mathrm{e}} \rho \mathrm{v}_{\mathrm{d}}

Hence, graph between \mathrm{v}_{\mathrm{d}} and \mathrm{E} will be straight line passing through the origin.
