Understanding Capacitors A. Basic Principles of Capacitance 1. Definition of Capacitance Capacitance is the ability of a component to store an electrical charge. It is defined as the ratio of the electric charge (Q) stored on one plate of the capacitor to the voltage (V) across the plates. The unit of capacitance is the farad (F), which is a large unit; in practice, capacitors are often rated in microfarads (µF), nanofarads (nF), or picofarads (pF). 2. How Capacitors Store and Release Energy Capacitors consist of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric field is created, causing positive charge to accumulate on one plate and negative charge on the other. This stored energy can be released when the circuit requires it, making capacitors vital for smoothing out voltage fluctuations, filtering signals, and providing bursts of energy. B.
