A current of 77 mA in a conducting wire of an unknown material is carried by free electrons. The cross-sectional area of the conductor is 1.5×10*-6 m2.Find the density of free electrons in the material if the average speed of the free electrons along the wire is 0.18 mm/s. Use a value of 1.6×10*-19 C for the electron charge.
