\section{Introduction}
Electronic components are fundamental building blocks used \textbf{in electronic circuits} to manipulate electrical signals. They come in various forms and have different functions, but all play a crucial role in the functioning of electronic devices. Understanding the basic components is essential for anyone interested in electronics. This article provides a brief introduction to some common electronic components and their functions.
\section{Resistor}
A \textbf{resistor} is a passive two-terminal electronic component used to restrict the flow of electrical current. It is commonly made of a material with high resistance, such as carbon or metal. The resistance of a resistor is measured in ohms ($\Omega$) and determines how much current can flow through it when a voltage is applied.
\section{Capacitor}
A \textbf{capacitor} is a passive two-terminal electronic component used to store and release electrical energy. It consists of two conductive plates separated by a dielectric material. Capacitors are commonly used in filtering, timing, and frequency selection circuits, as well as energy storage and power supply applications.
\section{Inductor}
An \textbf{inductor} is a passive two-terminal electronic component used to store energy in a magnetic field. It consists of a coil of wire wound around a core material. Inductors are commonly used in applications such as filtering, energy storage, and signal processing.
\section{Diode}
A \textbf{diode} is a two-terminal electronic component that allows current to flow in only one direction. It acts as a switch, allowing current to pass through when its anode is at a higher potential than its cathode. Diodes are commonly used in rectifier circuits, voltage regulation, and signal demodulation.
\section{Transistor}
A \textbf{transistor} is a three-terminal electronic component used for signal amplification, switching, and voltage regulation. It consists of three layers of semiconductor material. Transistors come in different types, including bipolar junction transistors (BJTs) and field-effect transistors (FETs).
\section{Integrated Circuit}
An \textbf{integrated circuit} (IC) is a miniaturized electronic circuit that contains multiple electronic components on a single semiconductor chip. ICs can be analog or digital and are widely used in various electronic devices, including computers, smartphones, and televisions.
