Description

General Physics II Ch 18 Summary Chapter 18 comprises of the concepts of electrostatic forces and fields as well as, electric potentials and electrostatic potential energy. Electrostatic forces or the Coulomb force are the forces of attraction or repulsion between charges. Coulomb's Law represents the forces between charges with the following formula F=k[q1q2]/r^2 and was introduced by Charles Augustin de Coulomb in 1785. The next concept pertains to electric fields which are comprised of a distribution of electric charges while attracting or repelling surrounding charges. Michael Faraday invented the concept of the electric field and field lines in 1831.Electrostatic potential energy is the energy located in an electric field containing a charged particle at rest. The formula is Fe= -(1/4piE0)(Qq/r^2)r. In 1778, the concept of electric potential was discovered by a scientist named Alessandro Volta. It is defined as the amount of work required in order to move a unit charge from an infinite point to another point opposite an electric field...
