Potentielle elektrische Energie in einem gleichmäßigen elektrischen Feld
When an electric field accelerates a free positive charge, it acquires kinetic energy. This process is analogous to an object being accelerated by a ...
Potentielle elektrische Energie von Zweipunktladungen
The electric potential energy of a test charge in a uniform eclectic field can be generalized to any electric field produced by static charge ...
Elektrisches Potential und Potentialdifferenz
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy ...
Auffinden des elektrischen Potentials aus dem elektrischen Feld
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where ...
Berechnungen des elektrischen Potentials I
Consider a ring of radius R with a uniform charge density λ. What will the electric potential be at point M, which is located on the axis of the ring ...
Berechnungen des elektrischen Potentials II
An electric dipole is a system of two equal but opposite charges, separated by a fixed distance. This system is used to model many real-world systems, ...
Potentialäquipotentialflächen und Feldlinien
Electric potential can be pictorially represented as a three-dimensional surface. On such a surface, the electric potential is constant everywhere. The ...
Potentialausgleichsflächen und Leiter
For a conductor in which all charges are at rest, the conductor's surface is equipotential. The electric field is always perpendicular to ...
Bestimmung des elektrischen Feldes aus dem elektrischen Potential
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 ...
Poisson- und Laplace-Gleichung
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 ...
Van-de-Graaff-Generator
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. ...
Energie, die mit einer Ladungsverteilung verbunden ist
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 ...
Elektrostatische Randbedingungen
Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it ...
Zweiter Einzigartigkeitssatz
Consider a region consisting of several individual conductors with a definite charge density in the region between these conductors. The second uniqueness ...
