Hi forum
I need to explain the following to pupils of about 17 years of age.
2 questions regarding free electron kinetic energy transfer to copper wire (or resistor) material atoms in an electrical circuit.
1. I am confused as in which situation free electrons in a circuit transfer energy to heat a copper wire. Is it electrons that are free of their atom or electrons that jump to other outer valence bands of (copper wire) atoms?
2. How do free electrons actually transfer energy (kinetic) to (copper wire) atoms? How do they vibrate the copper wire atoms to heat the wire? Do they collide or some other mechanism?
Thank you for your time reading this. I hope I have made myself clear
Regards
Andy
