Two conductors of the same length are made of the same material, but with different cross-sectional areas, and are connected in series in the circuit. In which of them the most heat is released at the same time? Why?
More heat will be released on the wire, the cross-sectional area of which is larger, because the resistance is inversely proportional to the cross-sectional area, and according to the Joule-Lenz law, the released amount of heat is inversely proportional to the resistance at equal voltage.
