Passive Component
Aug 21, 2018

If an electronic component works without any form of internal power supply, it is called a passive component.

From the point of view of circuit nature, passive components have two basic characteristics:

 (1) it does not consume electricity or convert electricity into different forms of energy.

 (2) just input signals and operate without external power supply.

 Passive component: A circuit element that does not affect the basic characteristics of a signal but allows it to pass through without changing it as opposed to an active component. The most common are resistors, capacitors, inductors, transformer and so on.
