The derivation for E = V/d is based on the definition of electric field as the force per unit charge. The equation states that the electric field (E) between two parallel plates of a capacitor is equal to the potential difference (V) between the plates divided by the distance (d) between them.

The relationship between V and E for parallel conducting plates is E = V / d. (Note that Δ V = VAB in magnitude. For a charge that is moved from plate A at higher potential to plate B at lower potential, a minus sign needs to be included as follows: –Δ V = VA – VB = VAB. See the text for details.)
From a physicist’s point of view, either ΔV or E can be used to describe any charge distribution. ΔV is most closely tied to energy, whereas E is most closely related to force. ΔV is a scalar quantity and has no direction, while E is a vector quantity, having both magnitude and
28 paź 2019 · Is $E=−V/d$ or $E=V/d$ in an equal electric field. It can be both. It depends on what your scenario is. Remember that voltage is energy (work $W$) required per charge $q$. We could write your formula as: $$E=\frac{W}{q}/d$$
