Review Part A Recall that the density J of current flowing through a material can be written in terms of microscopic properties of the material: j = nqua, where n is the density of current carriers, q is the charge of one current carrier, and va is the drift velocity of a current The drift velocity is the component of the current-carrier's velocity due to acceleration from the electric field in the conductor. This corresponds to the average speed of all of the current carriers in the conductor. carrier. In a metal, the current carriers are electrons. The current carriers also have random thermal motions, but the randomness causes the velocities due to thermal motion to cancel when averaged over a large number of current carriers. If the electric field inside of the conductor has magnitude E, and the charge q is accelerated from rest for a time T, what is the final speed v of the charge? Express the speed in terms of E, q, T, and the mass m of the charge.
