Electric energy plays a major role in every aspect of modern life. However, efficient use of electric energy is not limited to the supply of active power. Another important parameter in electrical systems is reactive energy. Although reactive energy is often overlooked, it has a significant impact on energy efficiency. The management and control of reactive energy are achieved through compensation methods.Reactive EnergyReactive energy is a type of energy required for the operation of devices co

A battery is a rechargeable power source that stores electrical energy chemically and releases it as electrical energy when needed. It is used in automobiles to start the engine, power lighting systems, and supply electronic components. Batteries are typically manufactured using lead-acid technology.Structure and Operating PrincipleA battery consists of positive and negative plates, an electrolyte (a mixture of sulfuric acid and pure water), a case, terminals, and a cover. Chemical energy is con

A transformer is a static electrical machine that transfers energy between two or more circuits, typically at different voltage and current levels, without changing the frequency, through magnetic induction. Transformers, one of the fundamental pillars of the electrical system, enable the conversion of electrical energy from the high voltage levels at which it is generated in power plants to even higher voltages for efficient long-distance transmission, and then step-by-step reduction through di

The piezoelectric effect is a physical phenomenon in which certain crystalline and ceramic materials generate an electric charge in response to applied mechanical stress. This property arises from changes in polarization at the atomic level, particularly in materials with a crystalline structure. The term “piezoelectric” is derived from the Greek word “piezein,” meaning “to press” or “to squeeze.”This phenomenon is bidirectional: the first is the direct piezoelectric effect, in which an electric
