When a potential difference is applied to a certain copper wire, a current of $1\mathrm{.}5$ A passes through the wire.$$If the wire was removed from the circuit and replaced with a copper wire of twice the diameter, what current would flow through the new wire?$$Assume the wires are identical in all other aspects.

$0\mathrm{.}38$ A$$

$0\mathrm{.}75$ A

$1\mathrm{.}5$ A

$3\mathrm{.}0$ A

$6\mathrm{.}0$ A
