Electrical Energy & Capacitance Pgs. 665 - 682

Electrical potential energy Potential energy associated with an object due to its position relative to a source of electric force Electrical potential energy is a form of mechanical energy

Electrical potential energy can be associated with a charge in a uniform field Uniform field – field that has the same value and direction at all points Change in electrical potential energy depends on the charge, the strength of the electrical field, and the displacement

Electrical potential energy can be associated with a pair of charges

The electrical potential energy associated with an electron and a proton is -4.35 x 10-18 J. What is the distance between these two charges?
