With the help of energy bands explain how conduction takes place in conductors.
On the basis of energy band materials are categorized as conductor is given below:
Conductors: Substances as copper, aluminium and silver that permit the passage of current through them are conductors. The valence band of such substances overlaps the conduction band as demonstrated in figure. Because of this overlapping, a large number of free electrons are available for conduction. It is the purpose, why a slight potential difference applied across them causes a heavy flow of current throughout them.

Hi I have just received a math assignment and was wondering if you can take a look at it and tell me if you can be finished before the 12th of february and what the cost will be.
A manager has determined the cost C, in dollars, for manufacturing is C(q) =85log 10 (10+q/2) for manufacturing, where q is the number of units produced in a given day. (a
