Question

A cylindrical conducting wire carries a current of 3.8 A. If the density of the conduction electrons (free electrons) in the wire is n=6.6!10^28m^-3 and the magnitude of the drift velocity of the electrons within the wire is v=40!m/s, determine the diameter of the wire. Express your answer in units of mm using one decimal place. Take the charge of the electron e=1.6!10^-19C.

Step 1

Step 1: Calculate the area of the wire using the formula A = I / (n * e * V), where I is the current, n is the electron density, e is the charge of the electron, and V is the drift velocity. Show more…
