A circuit is constructed from two batteries and two wires, as shown in the diagram below. G B X X Battery 1 X X Battery 2 Each battery has an emf of 1.7 volts. Each wire is 28 cm long, and has a diameter of 0.0007 meters. The wires are made of a metal which has 7e+28 mobile electrons per cubic meter; the electron mobility is 4e-05 (m/s)/(V/m). A steady current runs through the circuit. The locations marked by "x" and labeled by a letter are in the interior of the wire. Which of these statements about the electric field in the interior of the wires, at the locations marked by "x"s, are true? Check all that apply. The magnitude of the electric field at location D is larger than the magnitude of the electric field at location C. O At location B the electric field points to the left. At every marked location the magnitude of the electric field is the same.What is the magnitude of the electric eld at location E? EE = V/m How many electrons per second enter the positive end of battery #2? 1:] electrons/s If the cross-sectional area of both wires were increased by a factor of 3, what would the be magnitude of the electric field at location E? new value of EE = :] V/m Which of the diagrams below best shows the approximate distribution of excess charge on the surface of the circuit? ---Select v
