Which effect does not apply to the movement of electrons flowing in a conductor?

• A. Thermal energy
• B. Magnetic energy
• C. Electrical energy
• D. Kinetic energy

Answer: (A)

When electrons flow in a conductor, they carry electrical energy as they move, and their motion creates a magnetic field around the conductor, which corresponds to magnetic energy. The electrons themselves are physically moving, so they have kinetic energy as well. Heat, or thermal energy, only appears as a byproduct when the moving electrons collide with the atoms in the material and the energy is dissipated due to resistance. In an ideal conductor with no resistance, that heat wouldn't be produced. So thermal energy is not an inherent effect of the movement itself; it depends on resistance and energy dissipation. The direct effects of the moving charges are electrical energy transport, magnetic energy from the magnetic field, and kinetic energy of the moving electrons.
