When electric current passes through a metallic conductor, its temperature rises. This is due to__________?
Correct answer: A. collisions between conduction electrons and atoms
- A. collisions between conduction electrons and atoms
- B. the release of conduction electrons from parent atoms
- C. mutual collisions between metal atoms
- D. mutual collisions between conducting electrons
Explanation
Conduction electrons transfer energy to the metal lattice through collisions with atoms. This increases atomic vibration and appears as a rise in the conductor’s temperature.
