Capacitor Basics in Electronics

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

In this article, we will explore the purpose of a capacitor in a circuit and how it contributes to the overall functionality of electrical systems.

How does a capacitor work in a DC Circuit?

When discussing how a capacitor works in a DC circuit, you either focus on the steady state scenarios or look at the changes in regards to time. However, with an AC circuit, you generally look at the response of a circuit in regards to the frequency. This is because a capacitor’s impedance isn’t set - it’s dependent on the frequency.
