In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effe

Capacitor

The most common group is fixed capacitors. Many are named based on the type of dielectric. For a systematic classification, these characteristics cannot be used because one of the oldest, the electrolytic capacitor, is named instead by its cathode construction. In most practical applications, each conductor of a capacitor initially has zero
