List of Types of Basic Electronic Components, Functions, Symbols.
Basic Electronic Components are electronic devices or parts usually packaged in a discrete form with two or more connecting leads or metallic pads. These devices are intended to be connected together, usually by soldering to a Printed Circuit Board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, oscillator, wireless).
Some of the Basic Electronic Components are: resistor, capacitor, transistor, diode, operational amplifier, resistor array, logic gate etc.
Types of Electronic Components
These are of 2 types: Passive and Active Components. Both these types of components can be either Through-Hole or SMD.
1. Passive Components
These components are those that do not have gain or directionality. They are also called Electrical elements or electrical components.
Example: Resistors, Capacitors, Diodes, Inductors.
2. Active Components
These components are those that have gain or directionality.
Example: Transistors, Integrated Circuits or ICs, Logic Gates.

Basic Electronic Components and their Functions
Resistors
Function: Resistors are perhaps the most fundamental of electronic components. Their primary function is to limit or regulate the flow of electrical current in a circuit, and they are used to control the voltage and current within the circuit.
Application: You'll find resistors in almost every electronic device, used to adjust signal levels, terminate transmission lines, cables, and much more.
Capacitors
Function: Capacitors store electrical energy temporarily and release it when needed. They are used to smooth out fluctuations in electrical supply, filter signals, and store energy in power applications.
Application: Capacitors are commonly found in power supplies, electronic filters, and signal processing circuits.
Inductors
Function: Inductors, like capacitors, store energy, but they do so in a magnetic field created by an electric current. They are used to control current and filter out unwanted frequencies in a circuit.
Application: Inductors are often used in radio-frequency applications, power supplies, and in conjunction with capacitors to create tuned circuits.
Diodes
Function: Diodes allow current to flow in one direction only, acting as a one-way valve. They are essential for converting alternating current (AC) to direct current (DC).
Application: Diodes are used in power supplies, signal demodulation, and protection circuits to prevent reverse current flow.
Transistors
Function: Transistors are used to amplify or switch electronic signals and electrical power. They are the building blocks for modern electronic devices.
Application: Transistors are found in almost every electronic device, from radios and televisions to computers and mobile phones.
Integrated Circuits (ICs)
Function: Integrated Circuits are miniaturized circuits consisting of several electronic components such as resistors, transistors, and capacitors. They are designed to perform various functions, from simple logic gates to complex microprocessors.
Application: ICs are used in virtually all electronic equipment, including computers, smartphones, and even household appliances.
Electronic components are the fundamental building blocks of modern technology. Understanding the basic function of each component is crucial for anyone interested in electronics, whether for professional development, education, or hobbyist projects. Each component has a specific role, but it's their combination and interaction that create the complex functionalities in today's electronic devices. As technology continues to advance, these components will evolve, but their core functions will remain integral to the design and operation of electronic systems.
Circuit Symbols of Electronic Components
In electronic schematics, different circuit symbols are used to represent various electronic components. Understanding these symbols is essential for reading and designing electronic circuits. Here's a description of the circuit symbols for common various electronic system components:
Resistor: Represented by a zig-zag line. Resistors impede the flow of current in a circuit. The symbol may vary slightly between American and European styles.
Capacitor: Illustrated as two parallel lines with a gap between them, symbolizing the plates of the capacitor. Polarized capacitors, like electrolytics, have a curved line to indicate the negative plate.
Inductor: Shown as a series of curved or angled lines, representing the coils of wire in an inductor.
Diode: Depicted as a triangle pointing to a line. The triangle represents the direction of conventional current flow (anode to cathode). For Light Emitting Diodes (LEDs), arrows pointing away from the diode symbol indicate light emission.
Transistor: There are various symbols for different types of transistors. Bipolar Junction Transistors (BJTs) have a symbol with three leads (emitter, base, and collector). Field-Effect Transistors (FETs) are represented with a line and a curve.
Integrated Circuit (IC): Often shown as a rectangle with lines coming out of each side, representing the input and output pins. The complexity inside the IC is not depicted in the symbol.
Transformer: Illustrated as two coils (lines or rectangles) near each other, symbolizing the inductive coupling. A dashed line or two parallel lines between the coils may represent the core.
Switch: Represented by a break in a line with a lever-like symbol. The design varies depending on the type of switch (e.g., pushbutton, toggle).
Battery: Shown as a pair of lines of different lengths, representing the positive and negative terminals. Multiple pairs in series can represent a multi-cell battery.
Ground: Indicated by a set of one to three horizontal lines of decreasing width, symbolizing the earth ground.
Crystal Oscillator: Depicted as a rectangle with two leads. Sometimes, it's shown with two small capacitors connected to ground, representing the load capacitance.
Fuse: Shown as a rectangle or a line with a break in the middle, indicating the fuse element.
Potentiometer: Represented by an arrow across or through a resistor symbol, indicating an adjustable resistance.
Variable Capacitor: Illustrated similarly to a standard capacitor but with an arrow through it, indicating adjustability.
Relay: A rectangle (representing the coil) with a line showing the switch that is actuated by the coil.
Light Bulb: Represented by a circle with a cross or loop inside, symbolizing the filament.
Each of these symbols is standardized for easy recognition and is used globally in electronic circuit diagrams. Knowing these symbols is crucial for anyone involved in electronics, from hobbyists to professional engineers.
