Two distinct wires connected in series with an ideal battery.
Two distinct wires connected in series with an ideal battery.
Two cylindrical wires, Wire 1 and Wire 2, are made of different conductive materials such that Wire 1 has a lower resistivity and a smaller cross-sectional area than Wire 2. The two wires are connected end-to-end in series with an ideal battery to form a complete DC circuit operating at steady state. How does the electric current \(I_1\) in Wire 1 compare to the electric current \(I_2\) in Wire 2, and what physical principle justifies this comparison?
