Source sentences:
text: In an ideal case, cross-section and physical composition of the examined material are uniform across the sample, and the electric field and current density are both parallel and constant everywhere.
text: As shown below, this expression simplifies to a single number when the electric field and current density are constant in the material.
text: If the electric field is constant, the electric field is given by the total voltage V across the conductor divided by length ℓ of the conductor: E = V ℓ {\displaystyle E={\frac {V}{\ell }}} If the current density is constant, it is equal to the total current divided by the cross sectional area: J =
