Introduction to Electronic Circuits: Active vs. Passive Components
Active and passive electronic components distinguish between themselves, while circuits are determined by their active and passive components. Learning to identify active and passive components and how these components are connected to the circuits is important for circuitous use.
Electronic Circuits: Active vs. Passive Components Article
In electronic circuits, there are two main types of components: active and passive. Active components, such as transistors and integrated circuits, require a power supply to operate, while passive components, such as resistors and capacitors, do not. Active components can amplify or switch electrical signals, while passive components can only filter or delay them.
According to electronic engineers, the terms “active” and “passive” are used to define the parts and circuits of a device or circuit that are directly responsible for increasing a signal. In this article, we will be exploring active versus passive components and their precise roles in circuits.
The purpose of this article is to provide an introduction to electronic circuits, specifically active and passive components. Passive components are the simplest type of component and are made from materials that do not require electrical power to operate, such as resistors and capacitors. Active components, such as transistors and integrated circuits, require electrical power to operate.
In this article we will learn about the components and operation of transistors, diodes, integrated circuits and the basic electrical circuit. We will also learn how to use resistors and capacitors in circuits.
What is a transistor?
A transistor is a semiconductor device that can act as an amplifier, a switch and even as a light source. They are widely used in all kinds of electronic circuits such as amplifiers, radios, TVs and computers.
Active Components and Passive components
An active component is an electronic device that requires power to operate. An active component may consist of a small number of transistors, integrated circuits and other components. Active components include amplifiers, oscillators and the like. A passive component does not require power to operate.
Active Components
The active components of an electronic circuit are the devices that provide the power and control signals to the circuit. The three most common active components are transistors, integrated circuits, and diodes. Each type of component has unique properties that make it suitable for a particular application.
Examples of active components; a microcontroller, a power MOSFET, and an IC
Passive Components
Passive components are essential for creating circuits with specific functions. The most common type of passive component is the resistor, which is used to control the flow of electricity through a circuit.
Passive components are relatively easy to manufacture and include resistors, inductors, and capacitors.
Passive components will always experience loss. Inherent losses indicate a decrease in power between the input and output signals, as well as a decrease in amplification.
For instance, a transformer can boost the voltage of an electric signal during step-up configurations. As a result, the transformer’s output power will be equal to or less than that of its input, and the transformer is only useful for power factor correction.

Determining Electronic circuit active and inactive components
It can be difficult to determine whether a component is active or passive. For example, diodes are often misidentified as active parts, but they are actually passive. Whether a component can control a current using another often determines whether its behavior is passive or active.
Another option is to identify a particular element that is involved. For instance, in the case of a tunnel diode, it is designed for quick operation. Its normal operating range exhibits zero resistance while increasing the input power reduces the electric current contained — which makes it an oscillator. This function makes it an active component.
This is a very useful tool for determining what electronic components are in a circuit and whether or not they are active
A part users often take into consideration is a relay. A relay includes a switch triggered by a coil and can be used for switching high power sources with an intake of low power. Relays are digital and could be considered an oscillator, but they can be utilized to make logical gates and even computers, making them passive.
