Resistors are fundamental components in electrical circuits, designed to control the flow of electric current by providing resistance. Available in various materials and resistance values, resistors are used in countless applications to regulate voltage, limit current, and protect sensitive components from damage. Resistors are essential in power supplies, signal processing circuits, and consumer electronics.

Whether you're building a simple LED circuit or a complex electronic system, resistors play a critical role in ensuring the stability and reliability of the circuit. With various types like fixed, variable, and precision resistors, these components are a staple in every electronics toolkit.
