Summary
Objects become electrically charged or uncharged by transferring charges
Two different charges exist: positive and negative
In Isolated systems the total charge is conserved
Like charges repel, unlike charges attract
The electric force between two charges is given by the Coulomb law
Electric charges are surrounded by an electric field equal to the force experienced by a unit charge
electric potential characterizes energetically the electric field
The electric potential energy gives the work made against the electric field, when we bring the given charge from a zero reference location to the given point
The electric potential equals the electric potential energy divided by the objects charge
