A 50-W LED light bulb is supplied with 0.5 A current using a copper wire with diameter 1.628 mm. What is the magnitude of the current density and magnitude of the drift velocity? Assume one free electron per Cu atom. The density and mass of Cu is 8.80 x 10^3 kg/m^3 and 63.54 g/mol, respectively. (1 mol = 6.02 x 10^(23) atoms, charge of each carrier = 1.60 x 10^(-19) C).
