What is so called SELF ENERGY?

  1. Mar 16, 2004 #1
    What is so called SELF ENERGY? I know the explanation that it is the energy that a point charge has when it is by itself,at a large distance from other charges. In textbook (ohanian) says that it takes work to assemble the point charge out of infinitesimal pieces of charge.The energy needed to assemble the point charge is called the self-energy of the point charge.I know that this explanation is clear enough.But as i know e=1.6*10^-19 C , the charge of electron or proton is the smallest charge, and all other charges are INTEGER*e.So I thought that I can assume that self energy of an electron is zero.But I learned that it turns out to be Infinite...
