Marks: +1, -0

What is the relationship between the potential difference across a conductor and the current flowing through it ?

${V}+{I}$ is a constant
${I} \/ {V}$ is a constant
${V} \×{I}$ is a constant
V/I is a constant

Solution:

The relationship between the potential difference across a conductor and the current flowing through it is

{V} \/{I}

is constant. Ohm's Law deals with the relationship between voltage and current in an ideal conductor, which states that potential difference (voltage) across an ideal conductor is proportional to the current through it.
