Hi I'm doing a scool project on resistance and my question baffaled my teacher so I though I'd ask you guys. While passing a current through a wire, how exactly does electrical energy get transfered to kenetic energy to heat up the wire. Some people say that the energy is transfered becuase the electrons crash into the nucleus of the atoms which make up the wire, but my teacher said that the electrons never actually touch the nucleus. If they never touch then how is heat produced? Also when the electrical energy is transfered to heat energy do the electrons just disappear and if not do they carry on and still produce a current.
Re: How exactly does resistance cause heat increase?
