This article explains active and passive electronic components, their roles in circuits and difference between active and passive electronic
Active components (such as transistors, integrated circuits, and diodes) require an external power source to operate. They are capable of signal amplification, switching control, or energy conversion, and serve as the core elements in modern electronic systems for signal processing and power control. In contrast, passive components (such as resistors, capacitors, inductors, and transformers) do not rely on an external power source. They are mainly used for auxiliary functions such as energy storage, voltage division, filtering, and current limiting.
