A conductor with cross-sectional area 6 cm^2 carries a current of 15 A.
If the concentration of free electrons in the conductor is 9 × 10^28 electrons/m^3 , what is the drift velocity of the electrons? Answer in units of mm/s.

I used Q=d*A*V and got -1.733e-19 mm/s, but this is wrong (as is the positive value since its velocity…)
