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.

Your instructor may ask you to turn in this work.) (b) On a copy of the diagram, draw the electric field inside the wire at the 3 locations marked x. (Do this on paper. Your instructor may ask you to turn in this work.) (c) What is the magnitude of the electric field at location B? 240 X V/m (d) What does the voltmeter read, both magnitude and sign? V (e) What does the ammeter read, both magnitude and sign? A (f) In a 60 second period, how many electrons are released from the - end of the battery? electrons (9) There are 1.5 x 1026 free electrons per cubic meter in the wire. What is the drift speed v of the electrons in the wire? m/s (h) What is the mobility u of the material that the wire is made of? (m/s)/(V/m) (i) Switch meter 1 from being an ammeter to being a voltmeter. Now what is the reading on meter 1, both magnitude and sign? V
