The free electrons of a copper wire of cross-sectional area `10^(-6) m^(2)` acquire a drift velocity of `10^(-4) m//s` when a certain potential differ

The free electrons of a copper wire of cross-sectional area `10^(-6) m^(2)` acquire a drift velocity of `10^(-4) m//s` when a certain potential difference is applied across the wire. Find the current flowing in the wire if the density of free electrons in copper is `8.5xx10^(28) "electrons"//m^(3)`.
