Final answer:
The potential difference, VAB, between points A and B is equal to the change in potential energy divided by the charge.
Step-by-step explanation:
The potential difference, VAB, between points A and B is equal to the change in potential energy divided by the charge. Potential difference is commonly known as voltage and is represented by the symbol V.
VAB = (ΔΡΕ)/q = (VB - VA)/q
The potential difference can be expressed in terms of the electric field, distance between the points (x₂ - x₁), and position coordinates of the points (x₁, y₁ and x₂, y₂)
