# Question

A 340-km-long high-voltage transmission line 2.00 cm in diameter carries a steady current of 1,020 A. If the conductor is copper with a free charge density of 8.50 * 10^(28) electrons per cubic meter, how many years does it take one electron to travel the full length of the cable? (Use 3.156 * 10^7 for the number of seconds in a year.)
