Electric potential is amount of work required to move a unit charge from a reference point or surface to a specified point in an electric field. Accordingly, the energy possessed by a charged particle is due to its position with respect to the electric...

Electric potential is the potential energy per unit of charge associated with a static (time-invariant) electric field, also called the electrostatic potential, typically measured in volts. It is a Lorentz scalar quantity. The difference of electrical...

A growing interdependence between New England and Quebec has made Quebec a major player in the region's energy picture, a role that promises to expand over the coming decades. Quebec officials recognize that potential and are vigorously pursuing it. New England officials and business...

The arrival of the electric car has seemed inevitable for some years. We have been on the brink of a new form of transport for so long that the question must be: "Has the electric car got what it takes?" Amid renewed concern...
