Active and Passive Electronic Components
All about Active and Passive Electronic Components. Examples and Difference between Active and Passive Electronic Components
Active and Passive Electronic Components are two classes of electronic components. Both these classes of electronic components are different from each other. This article explains all about active and passive electronic components with examples and the difference between the two.
What are Active Electronic Components?
Active electronic components are those that can control the flow of electricity. Different Types of Printed Circuit Boards have at least one active component. Some examples of active electronic components are transistor, vacuum tubes, silicon-controlled rectifiers (SCRs).

Here is complete list of most common and widely used Active Electronic Components. I have not mentioned the Obsolete Components.
Integrated Circuits (IC)
What are Passive Electronic Components?
Passive electronic components are those that don’t have the ability to control electric current by means of another electrical signal. Examples of passive electronic components are capacitors, resistors, inductors, transformers, and some diodes. These can be either Thru-Hole of SMD Components.
Complete List of Passive Electronic Components
Here is complete list of most common and widely used Passive Electronic Components. I have not mentioned the Obsolete Components.
What is a Resistor?
A Resistor is an electrical device that resists the flow of electrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device.
What is a Capacitor?
A capacitor is a passive electrical component that can store energy in the electric field between a pair of conductors called “plates”. The process of storing energy in the capacitor is known as “charging“. The ability of a capacitor to store charge is measured by its capacitance.
Capacitors are used in electronic circuits as energy storage devices. They are also be used to differentiate between high-frequency and low-frequency signals. A wide variety of capacitors are available, including electrolytic capacitors, basic parallel-plate capacitors, and mechanical variable capacitors.
What is a Diode?
A diode is a one-way valve for electricity. Diodes allow flow of electricity in one direction. Most diodes have a painted line on one end showing the direction or flow. The negative side is normally white.
What is an Integrated Circuit (IC)?
Integrated Circuits (ICs) are package of several complex circuits. ICs are available in a wide variety of packages and sizes. Their applications are as varied as their packages.
What are Transistors?
A transistor is a semiconductor device. It is the fundamental building block of the circuitry in mobile phones, computers, and several other electronic devices. A transistor has very fast response and is used in a number of functions including voltage regulation, amplification, switching, signal modulation, and oscillators.
Transistors may be packaged individually or they can be a part of an integrated circuit. Some of the ICs have billion of transistors in a very small area.

Active and Passive Electronic Components
Electronic components, both active and passive, are lifeline of any Printed Circuit Board assembly. They both play vital roles in the functioning of any electronic device. Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function.
