Two copper wires A and B have the same length and are connected across the same battery. If
RB = 8RA,determine the ratio of their cross-sectional areas.
Please tapy answer
ou have a summer job as an assistant technician for a telephone company in California.During a recent earthquake, a 1.0-mile long underground telephone line is crushed atsome point. This telephone line is made up of two parallel copper wires of the samediameter and same length, which are normally not connected. At the place where theline is crushed, the two wires make contact. Your boss wants you to find this placeso that the wire can be dug up and fixed. You disconnect the line from the telephonesystem by disconnecting both wires of the line at both ends. You then go to one end ofthe line and connect one terminal of a 6.0-V battery to one wire, and the other terminalof the battery to one terminal of an ammeter. When the other terminal of the ammeteris connected to the other wire, the ammeter shows that the current through the wire is1.0 A. You then disconnect everything and travel to the other end of the telephone line,where you repeat the process and find a current of 1/3 A.
