[SOLVED] Another Current and Drift Velocity Question 1. A car's starter motor draws 50 A from the car's battery during startup. If the startup time is 1.5 s, how many electrons pass a given location in the circuit during that time? 3.As current = rate of flow of charge, I = q/t Charge, q = I.t = 50 x 1.5 = 75 C 1 electron has charge, e = 1.6x10^-19 C And q = N.e Number of electrons which pass in 1.5 s, N = q/e = 75 C/1.6x10^-19 C = 4.69x10^20 electrons OR use this equation:I = ne/dt and get: n = 50 x 5 = 250 e 1.6 x 10-19 = 156.25 x 10^19 = 1.56 x 10^21 electrons 1.56 x 10^21 electrons pass during that time. Which solution/answer is correct?
