When the tail light of a car is turned on, 0.5 A flows throughthe wires. The length of one wire from the battery to the taillight is 5.0 meters.Estimate how long you think it will take anelectron to travel from the battery to the tail light and how manyelectrons flow through the tail in one minute. Thank you!
Given :
14AWG copper wire is used, which has a cross sectional area of2.1e-6 m^2
2 The density of copper is 8.96 grams/cm^3
3 The atomic mass of copper is 63.5.
Each copper atom has one free electron.
(should be 3.3 days and 1.9e20 electrons per minute. How? )Please show each steps. Thank you so much!
