Question

10 Current ElectricityWe want to calculate how long it takes for an electron to get from a car battery to the starter motorthe ignition switch is turned. Assume that the current flowing is 115 A, and that the electrons tradethrough copper wire with cross-sectional area 31.2 mom and length 85.5 cm. What is the current dein the wire? The number density of the conduction electrons in copper is 8.49 102-/mº. Givennumber density and the current density, what is the drift speed of the electrons? How long does it tafor an electron starting at the battery to reach the starter motor? Assume no collision​
