Capacitor in Electronics – What It Is and What It Does

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

Understanding Capacitors

They act like a temporary storage device and hold this charge indefinitely as long as the supply voltage is present. Thus a capacitors charging current can be defined as: i = CdV/dt. It is important to note that capacitors in DC circuits do not have the continuous charging and discharging cycles as seen in AC circuits.

What is a Capacitor? Capacitor Types, Capacitor Uses, and Capacitor

A capacitor (historically known as a "condenser") is a device that stores energy in an electric field, by accumulating an internal imbalance of electric charge. It is made from two conductors separated by a dielectric (insulator). Using the same analogy of water flowing through a pipe, a capacitor can be thought of as a tank, in which the charge is often thought of as a
