The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
In this article, we will explore the primary functions of capacitors and how they contribute to the operation of electronic circuits. One of the most fundamental functions of a capacitor is its ability to store electrical energy. A capacitor consists of two conductive plates separated by an insulating material called a dielectric.
The maximum energy (U) a capacitor can store can be calculated as a function of U d, the dielectric strength per distance, as well as capacitor’s voltage (V) at its breakdown limit (the maximum voltage before the dielectric ionizes and no longer operates as an insulator):
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
When voltage is applied across a capacitor, it stores electric charge on its plates. When the voltage is removed, the stored charge is released, allowing the capacitor to discharge. Capacitors are used in various applications, such as filtering, energy storage, and timing circuits. What are the types of capacitors?
