24 mar 2023 · Electrical Energy Formula. Let’s say the potential energy at point A is denoted by U (A) while the potential energy at point B is denoted by U (B). U (A) = Q×V (A) U (B) = Q×V (B) Let the change in potential energy be denoted by U net. U net = Final Potential Energy – Initial Potential Energy. U net = U (B) – U (A) U net = {Q×V (B) – Q×V (A)}
