Figure 31.22 shows a rod made of three pieces of conducting material connected end to end. The pieces are of equal size but are made of different materials; pieces A and C have negligible resistance, but piece \(B\) has significant resistance. Consider connecting two oppositely charged plates to the ends of this rod. After the plates have been connected, how does the electric field in B compare with the electric field that existed between the plates before they were connected to the rod? Assume the charge on the plates is maintained.
