Four wires are made of the same highly resistive material, cut to the same length, and connected in series.

  • Wire 1 has resistance R1 and cross-sectional area A.
  • Wire 2 has resistance R2 and cross-sectional area 2A.
  • Wire 3 has resistance R3 and cross-sectional area 3A.
  • Wire 4 has resistance R4 and cross-sectional area 4A.

A voltage V0 is applied across the series, as shown in the figure. Find the voltage V2 across wire 2.

Explain the distinction between an ohmic and non-ohmic material, in terms of how the current and resistance behave as the voltage difference across the material is changed.

Now, imagine a single-loop circuit with a battery, two wires, and a 10 Ohm resistor. The wires are also ohmic, but with a resistance much smaller than the 10 Ohm resistor. Despite the disparity in resistance, the current in the wire is the same as that through the resistor since they are in series. Using Ohm's Law, explain how this uniformity in current relates to (or arises from) the individual potential differences across the wire and resistor.
