The electric field and electric potential are related to each other. If the electric field at various points in the region of interest is known, it can be ...
Ecuación de Poisson y Laplace
The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The ...
Generador Van de Graaff
Van de Graaff generators (or Van de Graaffs) are devices used to demonstrate high voltage due to static electricity that can also be used for research. ...
Energía asociada a una distribución de carga
The work done to bring a charge through a distance r is given by the potential difference between the initial and the final position. To assemble a ...
