Question

A copper wire of radius 2 mm and length 25 cm carries a current of 4.8 mA. Let the NET

number of electrons that move across a cross-section of the wire in 2 seconds be N. (Assume

that the wire is uniform and also that all the current flow is only due to flow of electrons). What

is the value of N / 1016? (charge on each electron is 1.6×10−19 C) ​
