ELECTRIC POTENTIAL Lecture Notes www.highschoolphysics.net 1 ELECTRIC POTENTIAL {Here is a quite different order of subjects to teach electric potential, going from concrete rules for memorizing, to applications of energy conservation. Definitions comes last. This may be incostistent, (for example we calculate and use electric potential in problem solving without knowing its meaning) but works in class. If you start the subject matter by defining potential as ?work needed to bring unit charge from infinity to a point?, you will probabily continue alone no matter how crowded the class is.} 1. Electric potential (?) and Potential Difference (??,U) Properties: a) Unit of potential is Volt. (Scalar quantity) b) Electric potential decreases as we go down the
