Problem

A conductor obeys Ohm’s law. Its VV–II graph passes through the origin and the point (8 V, 0.32 A)(8\,\text{V},\,0.32\,\text{A}). What current will flow when a potential difference of 20 V20\,\text{V} is applied across the same conductor? (a) 0.64 A0.64\,\text{A} (b) 0.80 A0.80\,\text{A} (c) 1.25 A1.25\,\text{A} (d) 0.32 A0.32\,\text{A}
