The discussion clarifies that wires do not heat up due to friction but rather due to resistance when current flows through them. In ideal conditions, such as with superconductors, there is no thermal excitation, and thus no heat is produced. However, in standard wires and resistors, the resistance causes atomic and molecular excitation, leading to heat generation. This phenomenon is critical in understanding electrical conductivity and thermal dynamics in materials.
