Two wires of the same length and cross-section, one made of copper and the other made of aluminum, are connected in parallel to a voltage source. Which one will be hotter after 30 seconds? What happens if you connect them in a series? Explain in words. (Paluminum = 2.8 x 10^-8 Ωm, Pcopper = 1.7 x 10^-8 Ωm)
