Unformatted text preview: electron density, but with electron mobility 3 times as large as that of Nichrome. Now what is the electric field inside the wire? 1.82 1.82 V/m The electron current in the first circuit (Nichrome) is i 1 . The electron current in the second circuit (wire with higher mobility) is i 2 . Which of the following statements is true? i 2 < i 1 Not enough information is given to compare the two currents. i 2 > i 1 i 2 = i 1 Solution or Explanation Use the loop rule. Note that the electric field inside the wire depends only on the length of the wire, and not on its mobility. Home My Assignments Extension Request...
