Consider the three pieces of wire in Figure 31.20. All three are made of the same material and have identical circular cross sections. Conductor A has length \(\ell\); conductors B and \(C\) have length \(2 \ell\). With the wires kept in the configurations shown, a positively charged conducting plate is connected to the left end of each wire and a negatively charged conducting plate is connected to the right end of each wire.
