Electric potential is simpler than electric fields because electric potential is a scalar quantity and, therefore, has no direction associated with it. Electric potential is more practical than the electric field because differences in potential, at least on conductors, are more readily measured ...
electric potential n. The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts. The static electric field is the negative of the gradient of the electric potential. ...
Difference of potential between two points is measured by the work necessary to carry unit positive charge from one to the other. If the work involved is 1 erg then there is the electrostatic unit of potential. The potential at a point due to charge q at a distance r in a medium ...

In an electrolyte, the flow of current is due to ions and In plasma—an ionized gas, the flow of current is due to ions and electrons. When an electrical potential difference is applied between two points in a conductive medium, an electric current starts flowing from higher potential to lo...
Electric potential is a scalar quantity that can be defined as the amount of work done in moving a unit positive charge (+1C) from one point to the other in an electric field. A charge q is present on a point object. The potential of the sphere at a distance r from it is giv...
Electric potential is the amount of work energy against the electric field to move a unit charge to a specific point. Current flow in a conductor is supported by electric potential difference and can also be used to control and drive charged motion....
Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Electric potential is measured in joules per coulomb (i.e., volts), and differences in potential are measured with a
