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.

Capacitor

V es la tensión aplicada al capacitor [Volt]. La capacitancia es la relación entre la carga eléctrica en una placa de un capacitor y la diferencia de tensión entre las dos placas, su valor depende de las dimensiones físicas del capacitor y de la permitividad del material dieléctrico con el que está construido.

What does the Voltage Rating on a Capacitor Mean?

The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain ...

What does the Voltage Rating on a Capacitor Mean?

So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it''s best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor). So when seeing the (maximum) working voltage specification on a datasheet ...
