By the end, you will have a comprehensive understanding of how capacitors work and their significance in modern technology. II. Basic Principles of Capacitance A. Definition of Capacitance Capacitance is a measure of a capacitor's ability to store charge. It is defined as the amount of electric charge (Q) stored per unit voltage (V) across the capacitor. The unit of capacitance is the Farad (F), which is a relatively large unit; in practice, capacitors are often rated in microfarads (µF), nanofarads (nF), or picofarads (pF). B. The Relationship Between Voltage, Charge, and Capacitance The relationship between voltage, charge, and capacitance is expressed by the formula: \[ C = \frac{Q}{V} \] Where: - \( C \) is the capacitance in Farads, - \( Q \) is the charge in coulombs, - \( V \) is the voltage in volts. This equation illustrates that for a given capacitor, the amount of charge it can store increases with the voltage applied across its plates. III. Structure of a Capacitor A. Components of a Capacitor A typical capacitor consists of two conductive plates separated by an insulating material known as a dielectric. The conductive plates are usually made of metals such as aluminum or tantalum, while the dielectric can be made from various materials, including ceramic, plastic, or electrolytic substances. B.
