Electronic components are parts or devices that are used in electronic circuits to control the flow of electrical current or to perform specific functions. They can be classified into two main categories: passive and active components.

Passive components include resistors, capacitors, inductors, and transformers. These components do not amplify or control the flow of electrical current but instead modify the voltage or current levels in a circuit.

Active components include transistors, diodes, integrated circuits (ICs), and other semiconductor devices. These components can amplify or switch electrical signals, generate oscillations, and perform other complex functions in electronic circuits.
