🔌 Fundamentals of Electronic Components

This paragraph introduces the basic classification of electronic components, distinguishing between passive and active components. Passive components, such as resistors, capacitors, and inductors, are essential for their non-amplifying roles in circuits. Resistors oppose current flow and are measured in ohms. Capacitors store and release electrical energy, measured in farads, and can be fixed or variable, with common types being mica, ceramic, paper, and argon. Inductors generate inductance, measured in henries, and are also available in fixed or variable configurations. Active components, which require an external energy source to control electron flow, include semiconductor devices like diodes, transistors, and integrated circuits. Diodes allow unidirectional current flow and are used in conversion circuits, with types such as PN, Zener, LEDs, and photodiodes. Transistors function as switches and amplifiers, controlled by voltage or current, and come in bipolar junction (BJT) and field-effect (FET) varieties. Integrated circuits are complex components with thousands of transistors and other elements on a silicon chip, used in modern devices like smartphones and computers, and can be analog or digital. The paragraph also briefly mentions display technologies like LCD, LED, and CRT, as well as power sources such as batteries, which convert chemical energy to electrical energy through electrochemical reactions and are categorized as primary (non-rechargeable) and secondary (rechargeable) cells.
