Why does cold metal conduct electricity better than warm metal?
The electrical conductivity of metals is due to the presence of mobile or free electrons present in the crystal lattice. The conductivity depends on temperature and the nature of the metals. It is guided by the electron sea or electron gas theory.
Answer and Explanation: 1
Metals has mobile electrons which are free to move anywhere in the crystal lattice. The conductivity of metals happens due to the presence of such...
