Passive components refer to electronic circuit elements that do not require a power source to perform their intended functions. Unlike active components such as transistors and integrated circuits, passive components do not amplify or control electrical signals. Instead, they alter the characteristics of the electrical signals that pass through them. Common passive components include resistors, capacitors, and inductors. Resistors impede the flow of electric current, capacitors store and release electrical energy, and inductors store energy in a magnetic field. These components are fundamental building blocks in electronic circuits, contributing to signal shaping, filtering, and impedance matching without actively controlling the flow of electrical charge.
