Circuit components are the basic building blocks of electrical circuits. They include items like resistors, capacitors, inductors, and diodes. Each component has a specific function, such as controlling current flow, storing energy, or allowing current to flow in one direction only. Understanding these components is essential for designing and analyzing circuits. In addition to these, transistors are crucial for amplifying signals and switching applications. Integrated circuits combine multiple components into a single package, making devices more compact and efficient. Together, these components work in harmony to create the electronic devices we use every day, from smartphones to computers.
