elektronkomponendid

Elektronkomponendid are the fundamental building blocks of electronic circuits. They are devices that control the flow of electric current and are essential for the operation of virtually all electronic devices, from simple calculators to complex computers and communication systems. These components can be broadly categorized into passive and active types.

Passive elektronkomponendid, such as resistors, capacitors, and inductors, do not require an external power source to operate and cannot amplify a signal. Resistors impede the flow of current, with their resistance measured in ohms. Capacitors store electrical energy in an electric field, measured in farads, and are used for filtering and energy storage. Inductors store energy in a magnetic field, measured in henries, and are often used in tuning circuits and transformers.

Active elektronkomponendid, on the other hand, require a power source to function and can amplify or switch electronic signals. Transistors are the most common active components, acting as electronic switches or amplifiers. Diodes allow current to flow in only one direction and are crucial for rectification and signal switching. Integrated circuits, or ICs, are complex components that contain a vast number of transistors, resistors, and other elements on a single chip, enabling sophisticated functionality in a small space. The development and miniaturization of elektronkomponendid have been key drivers of technological advancement.
