Sphärischer und zylindrischer Kondensator
A spherical capacitor consists of two concentric conducting spherical shells of radii R1 (inner shell) and R2 (outer shell). The shells ...
Kondensatoren in Reihe und parallel
Kondensatoren in Reihe und parallel
Multiple capacitors connected serve as electrical components in various applications. These multiple capacitors behave as a single equivalent capacitor, ...
Äquivalente Kapazität
Äquivalente Kapazität
Multiple capacitors can be connected in a circuit in series or parallel configuration. When the capacitor combination is connected to a battery, the ...

Kondensator mit einem Dielektrikum
Parallel plate capacitors consist of two conducting plates separated by a certain distance. However, it is mechanically difficult to hold the large plates ...
Dielektrische Polarisation in einem Kondensator
Dielektrische Polarisation in einem Kondensator
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, ...
Gaußsches Gesetz in Dielektrika
Gaußsches Gesetz in Dielektrika
Consider a polar dielectric placed in an external field. In such a dielectric, opposite charges on adjacent dipoles neutralize each other, such that the ...
Potenzial aufgrund eines polarisierten Objekts
Potenzial aufgrund eines polarisierten Objekts
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the ...
Suszeptibilität, Permittivität und Dielektrizitätskonstante
Suszeptibilität, Permittivität und Dielektrizitätskonstante
When placed in an external electric field, a dielectric material gets polarized. The charge density in the dielectric material is given by the sum of the ...
Elektrostatische Randbedingungen in Dielektrika
Elektrostatische Randbedingungen in Dielektrika
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the ...
