Extracted text: Consider a conductor of length L and cross-sectional area A. The material of which is constituted the conductor has resistivity p. Jin this Knowing that the current density conductor at constant temperature is linearly proportional to the electric field E find the relationship between the electric current i flowing this conductor and the p.d V applied to it.
