Most electronic components fall into two categories: Passive electronic components and active electronic components. To understand what passive electronic components are, it is first necessary to know what active electronic components are. Since all the functions of an electronic device depend on the distribution, regulation, and consumption of electrical energy, the difference and importance between passive and active electronic components becomes clear. Basically, it all boils down to how they deal with power.

Active electronic components need power in order to function. These types of components consist of integrated circuits and transistors. Integrated circuits perform various advanced functions in an electronic device, and transistors are designed to store amplify, and release power. Active components are needed in all electronic devices, but passive components are just as necessary.

What Are Passive Electronic Components?

Passive electronic components are also required in almost all electronic devices. In fact, you will find in many electronic devices made today that there are more passive electronic parts than active ones. This is due to the fact that modern computers and electronic hardware are moving towards utilizing smaller, more delicate components to carry out their functions. Limiting power usage to make such devices more energy efficient is also a concern, which is where passive electronic parts come into play.

Passive electronic parts do not need power in order to function. As a matter of fact, the purpose of most passive devices is to restrict and regulate power to circuits and components that would be overloaded and destroyed if they received too much electricity. Capacitors and resistors are examples of components that fall into the category of passive electronics.
