Capacitor Tutorial and Capacitor Basics Summary
The simplest construction of a capacitor is by using two parallel conducting metal plates separated through a distance by an insulating material. This insulating material is called the "dielectric". the dielectric plays an important role in the electrical operation of a capacitor and for this capacitor tutorial we can summarise the main …
6.1.2: Capacitance and Capacitors
At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1, negative charge will build up on the bottom plate while positive charge builds up on the top plate.
Why does capacitance not depend on the material of the plates?
$begingroup$ What you are learning about is an ideal capacitor, made from a material with zero electrical resistance. Of course such a thing doesn''t exist, but if the resistance is small, it is a pretty good approximation. In real-world applications capacitors are affected by their electrical resistance (even if they are made of good conductors like …
What is an Electrolytic Capacitors? Materials & Uses
We''ve seen an increase in niobium capacitors because:-A spike in the price of tantalum in the early 2000s helped encourage niobium usage in the West.-Like tantalum capacitors, niobium anodes include a mass of material formed around a wire conductor. This porous material undergoes oxidization to form a dielectric.

We will use Gauss''s Law to calculate the magnitude of the electric field between the two plates, far away from the edges. We can imagine a Gaussian surface Σ as shown in Figure 9.That is, Σ is the surface of a small rectangular parallelepiped, half of which lies outside the capacitor, and whose base faces are parallel to the plates. ...
