As, all the electrons will be oscillating along the polarisation of the Electric field, in what sense some electrons are free to move? | |

It’s not so much about the heat conductivity. And as you mention, the current goes to zero at the ends of the particle. High electric field -> “hot spot”; high current -> heat. These don’t occur at the same place. | |
