The electric potential inside a parallel-plate capacitor .

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.

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

By replacing you obtain:

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

hence, the answer is Qd/Ae0
