Transcribed Image Text:
A 46 cm long high-resistance wire with rectangular cross section 7 mm by 3 mm is connected to a 12 volt battery through an ammeter, as shown in the figure. The resistance of the wire is 59 ohms. The resistance of the ammeter and the internal resistance of the battery can be considered to be negligibly small compared to the resistance of the wire. Leads to a high-resistance voltmeter are connected as shown, with the - lead connected to the inner edge of the wire, at the top (location A), and the + lead connected to the outer edge of the wire, at the bottom (location C). The distance along the wire between voltmeter connections is d = 5 cm.
