You stick a fork in the electrical outlet. As you do, a spark jumps between the fork and the contact in the outlet. What is the maximum velocity (theoretical) of a single electron making that jump?

Wire A has a length of 4 m and a diameter of 2 mm. Wire B has a diameter of 8 mm. How long must it be to have the same resistance as Wire A?
