5 Essential Electronic Passive Components Every Engineer Should Know

Electronic passive components are essential in electronic circuits. These components don't require an external power source to function and use some other property to control the electrical signal. As a result, they only require the current traveling through the connected circuit. In this blog post, we will discuss five essential passive components in electronics that every engineer should know!

What is Resistor?

A resistor is an electronic passive component that has the ability to resist the flow of electricity within a circuit. As the name suggests, it works by “resisting” and limiting current flow in order to maintain a constant voltage on any electronic system. This is beneficial for electrical systems, as too much current running through a circuit can be dangerous to electronic components.

 In addition, resistors are often used in electronic circuits to create an adjustable time delay or provide an adjustable voltage divider when exposed to different levels of current. They are essential components of electronic circuits and without them many electronic projects could not be completed.

What is Capacitor?

A capacitor is a passive electronic component that can store energy in the form of an electric field. It consists of two pieces of conductive material, usually metal plates, separated by an insulating material called the dielectric. When voltage is applied to these plates, electrons will accumulate on one plate and the opposite charge will be present on the other plate, thus forming a potential difference between them.

 Capacitors are widely used and are available from passive components distributors. When combined with other passive components it can create complex electrical properties which are often used in interesting applications like passive filters or timing circuits.

Inductor

An inductor is an electronic passive component that stores energy in the form of a magnetic field. The inductor works by increasing or decreasing its electric current when exposed to changing conditions of electric or magnetic fields. It is among one of the most basic passive components used in electronic circuits, along with capacitors and resistors, to store, control and transfer electrical energy for various purposes such as filtering and providing power for electronic devices.

Inductors are mainly found in circuit boards, motors and other tools used commonly in electronic systems. The uses of an inductor include radio frequency filters, reactors, internal voltage regulators and transformers.

Diode

Diode is an electronic passive component designed to reliably allow current to flow in one direction only. It plays a critical role in electronic circuits as it regulates and directs the flow of electricity. By carefully controlling which direction currents are allowed to move in, these components ensure the stability and reliability of the electronic system.

Diodes consist of two terminals, with a semiconductor chip that allows electrons to flow from one terminal to another. When used properly, diodes help prevent electronic systems from being overloaded, overheating or short-circuiting. This makes them essential components for use in everyday electronic applications such as automotive, telecommunications, computers and more.

Transistor

Transistor Transistor are electronic passive components with three terminals. These electronic devices consist of two semiconductor materials that are used to amplify or switch electronic signals and electrical power. As a result, these transistor transistors are an essential part of most electronic products today in our modern world because they provide an efficient way to move electric energy from one point to another for almost any form of electronic device.

Transistor transistors are also highly sought after because they come in small sizes yet still have the ability to provide a compact, low-cost setup for the most complex electronic projects.
