    Answer:

    \Delta V=\frac{Q d}{A \epsilon_0}

    Explanation:

    for the calculation of the electric potential inside a parallel plate capacitor you can use the formula for the electric field inside the capacitor.

    \Delta V=V(d)-V(0)=\int_0^dEdx

    where d is the distance between plates and E is the electric field, which is given by:

    E=\frac{\sigma}{\epsilon_0}

    By replacing you obtain:

    \Delta V=E\int_0^ddx=Ed=\frac{\sigma d}{\epsilon_0}=\frac{Qd}{A\epsilon_0}

    where Q is the charge stored by the capacitor and A is the area of the plates.

    hence, the answer is Qd/Ae0
