Document Summary
1 c electric charge between the two points. The electric potential difference between any two points is defined as the work done to move a. The electric potential at any point in space is defined as the electric potential energy per unit (cid:3028)=(cid:1842)(cid:3028)(cid:1869) Potential difference is measured in volts (1 v = 1 j/c) and is sometimes referred to as voltage. The change in potential energy when a charge (cid:1869) moves through a potential difference (cid:3029)(cid:3028) is: The potential difference (cid:3029)(cid:3028) between two points (cid:1853) and (cid:1854) where a uniform electric field exists (cid:3029)(cid:3028)= (cid:1856) Where (cid:1856) is the distance between the two points. Relation between electric potential and electric field is given by: An equipotential line or surface is all at the same potential, and is perpendicular to the electric field at all points. infinity, is given by: The electric potential at a position (cid:1842) due to a single point charge (cid:1843), relative to zero potential at.
