Active and passive components:

Active components are those that can excite and amplify electrical signals, oscillate, control current or energy distribution and other active functions, and even perform data computation and processing when energy is supplied.

Active components include various transistors, integrated circuits, picture tubes, and displays.

In contrast to an active component, a passive component means that it cannot excite, amplify, oscillate, etc.

The response to the electrical signal is passive and compliant, and the electrical signal passes through the electronic component according to the original basic properties.

The most common resistors, capacitors, inductors, etc., are passive components.

(1) If there is an internal power supply when the electronic component works, such components are called active components and require energy to achieve their specific functions.

Active devices themselves also consume electrical energy, and high-power active devices are usually equipped with radiators.

2, resistors, capacitors and inductors can complete the specified function through the signal in the circuit, without the need for external excitation power, so they are called passive components.

Passive components consume very little electrical energy on their own, or convert electrical energy into other different forms of energy.

According to physical structure, circuit function and engineering parameters, active devices can be divided into discrete devices and integrated circuits.

Discrete components are related to integrated circuits (ics).

An integrated circuit (IC) is an electronic component that functions as a circuit by interconnecting transistors, resistance-capacitance sensors, and other components, as well as the wiring required in a class of circuits, so that they are located on one or more small semiconductor chips or dielectric substrates and packaged as a whole.

Discrete components refer to ordinary resistors, capacitors, transistors and other single electronic components, collectively referred to as discrete components. A discrete component is the smallest component with a single function, with no other component functional unit inside.
