First of all, thanks for your great efforts

I wish you answer my question quickly, because i have an exam this week,

1-Give reasons for :
- The surface of a conductor must be an equipotential surface
- The decrease of resistivity of a conductor by increasing ite temperature

2-what do you understand by Ohm law ???

3-Distinguish by equetions among:
-The (emf) & the source of (emf).

4-Drive an expression describe the electric field due to a charged infinite surface charge distribution .
(((does it mean that i have to drive an expression for the electric field due to very large non conducting plate ?????))))))

Thank you very much
