[[Electric Force, Field, and Potential]]

# Summary
|
|
* Electric potential is energy per charge: $V=\Delta U_E/q$ (Volts)
|
|
* Potential comes from multiple point charges added as scalars.
|
|
* Potential can be positive or negative, reference set at infinity.
|
|
* Electric field points towards decreasing potential. $|\vec E|=|\Delta V/\Delta r|$
|
|
* Equipotent lines (isolines) are perpendicular to field vectors. No work is done moving charge along equipotent.
|
|
* Conductors in electrical contact redistribute charge on the surface until it sits at the same potential. |
