Problem

A conductor obeys Ohm’s law. Its

V

–

I

graph passes through the origin and the point

(8\,\text{V},\,0.32\,\text{A})

. What current will flow when a potential difference of

20\,\text{V}

is applied across the same conductor? a)

0.64\,\text{A}

0.80\,\text{A}

1.25\,\text{A}

0.32\,\text{A}
