The energy balance for the ions is obtained by equating the energy gained from the electrons to the energy lost to neutral species. Since the heat capacity 共proportional to the number density兲 of the neutral species is several 共102 to ...

Electrical conduction
... In this chapter, we will treat conduction ‘e’ in metal as “free charges” that can be accelerated by an applied electric field, to explain the electrical and thermal conduction in a solid. Electrical conduction involves the motion of charges in a material under the Influence of an applied electric fi ...
