What is Passive Components and Active Components?

Which products are passive components? What is the difference between passive components and active components?

Generally speaking, passive components can operate without being connected to electricity, and can produce functions such as regulating current and voltage, storing static electricity, preventing electromagnetic interference, and filtering current impurities. Compared with the active component, when the voltage of the passive component changes, the resistance and impedance will not change with it.

1. Simple definition of passive components

  If the electronic component is working without any form of power supply inside, then this kind of device is called a passive device.

  In terms of circuit properties, passive devices have two basic characteristics:

  (1) Either consume electric energy by itself, or convert electric energy into other forms of energy.

  (2) It only needs to input signal, and it can work normally without external power supply.

2. Simple definition of active components

  If there is a power supply inside an electronic component when it is working, then this kind of device is called an active device.

  From the perspective of circuit properties, active devices have two basic characteristics:

  (1) It also consumes electric energy.

  (2) In addition to the input signal, an external power supply is also required to work normally.

  It can be seen that active devices and passive devices have completely different requirements and working methods for the circuit.
