A lightning bolt strikes one end of a steel lightning rod, producing a 14500-A current burst that lasts for 65 . The rod is 2.5 long and 2.1 in diameter, and its other end is connected to the ground by 38 of 8.1-mm-diameter copper wire.
A. Find the potential difference between the top of the steel rod and the lower end of the copper wire during the current burst.
(answer in volts, V)
B. Find the total energy deposited in the rod and wire by the current burst.
(answer in joules, J)
