The Electrostatic Potential Study Guide for Chapter 25 Outline 1. The Electrostatic Potential Every point in space has an . Potential is a electrostatic potential scalar that measures the potential energy per unit charge that a positive “test charge” would have if placed at the point: Z œ Y ; Here is the electrostatic potential and is the potential energy. Electrostatic potential is Z Y measured in volts (V), where volt joule coulomb (J C). " œ " Î Î The potential energy of a charge in an electric field is given by the formula ; Y œ ;Z Be aware that the exact values of and have no physical significance. Y Z Only differences in electrostatic potential (or potential energy) have physical significance . The electrostatic potential in the vicinity of a point charge is given by the formula Z œ " ; % < 1% ! This formula is calibrated so that far away from the charge (i.e. at infinity). Z œ ! Problems:
