drift velocity, resistance, electric fields, conductors... (1 Viewer)

I was wondering of nebody knows any info or any sites abt electron drift velocity, resistance, insulators, conductors, electric fields and the factors that affect resistance and ohm's law??

This is for the dot point: compare qualitatively the relative number of free electrons that can drift from atom to atom in conductors, semi conductors and insulators.

Thank you =)

Simplistic summary

Conductors: many

Semi conductors: some

Insulators: negligible amount/none

Do you have a textbook?

Ooh okay thanks a lot..
Ive only got the crappy macmillan tho i'll probably get jacaranda cuz i heard that was good...
