What Is Electric Potential Difference in Parallel Plates?

TL;DR

Electric potential difference between parallel plates is defined as the change in potential energy per unit charge, measured in volts. It is calculated using the equation ΔV = ΔU/Q, where ΔU is the change in electric potential energy and Q is the charge moved. For parallel plates, the potential difference also relates to the electric field strength and the distance between the plates.
