Two identical, parallel copper wires are placed under-ground between two points 1.00 mile apart. These wires are usually not connected, but a construction accident shorts the wires together at some point. To try to isolate the spot so that repair can be initiated, a technician goes to end A of the lines and finds that a 12.0-V battery connected across the wires at that end produces a current of 1.00A. Doing the same at the other end, B, produces a current of 0.20A. Is the break closer to end A or to end B?
