  \item Rewrite the current density using the average electronic velocity
        and find an expression for the conductivity $\sigma=1/\rho$.
- \item Obviously the resistance is caused by collisions of the electrons
+ \item The resistance is caused by collisions of the electrons
        with the lattice.
        Energy is not conserved in the collisions.
