The electric potential difference between two charges is measured in volts (how much energy [in electronvolts] per coulomb), and is the work required to separate the two charges against their attraction. To get further and further away from a charge you must exert more electric energy, which is converted into electric potential energy (much like kinetic/potential gravitational energies). Points that have the same electric potentials can be connected and called equipotential lines. After youre comfortable with equipotential line characteristics, you can move on to more electric potential topics.
The work done per unit charge in moving a charge between two points in an electric field is a scalar quantity known as the electric potential difference, or voltage.
The work done in move this charge is equal to the change in the object's electric potential energy (U=qV)
Equipotential lines show lines of equal electrical potential. They always cross electric field lines at right angles.
The electric potential due to a point charge is given by kq/r. To find the potential difference due to multiple point charges, add up the potentials due to each individual charge.
Equipotential lines show points of equal electric potential (similar to how topographic maps
show points of equal altitude, or gravitational potential).
As the distance between equipotential lines decreases, the steepness of the surface (or the gradient of the potential) increases.
Electric permittivity is a material property describing a material's ability to store energy in an electric field.
