All other things being equal, current will be larger in a wire that has a larger value of All other things being equal, current will be larger in a wire that has a larger value of:

a. conductivity.
b. resistivity.
c. the coefficient of current net charge.
d. potential.

a) conductivity

Explanation:

Assuming the wire obeys Ohm's Law, for a given voltage, in order to have a larger current, the resistance must be lower.The resistance of a resistive element is given by the following equation:

       

If geometric parameters keep the same, the only choice to lower the resistance value is diminishing the resistivity ρ.The resistivity, indeed, is defined as the inverse of the conductivity, σ.So, if resistivity decreases, conductivity increases.So, in order to have a larger current, all other things being equal, the wire must have a larger value of conductivity.The option a) is the right one.
