Current Density and Drift Speed A group of charges, each with charge q, moves with velocity v^vector. The number of particles per unit volume is n. What is the current density J^vector of these charges, in magnitude and direction? Make sure that your answer has units of A/m^2. We want to calculate how long it takes an electron to get from a car battery to the starter motor after the ignition switch is turned. Assume that the current...
