Resistors are passive electronic components that limit the flow of electric current in a circuit. They are fundamental to the operation of electronic devices, providing the necessary resistance to control voltage and current levels. Resistors are characterized by their resistance value, which is measured in ohms (Ω), and they play a crucial role in various applications, from simple circuits to complex electronic systems.
In electronic circuits, resistors serve multiple purposes, including voltage division, current limiting, and signal conditioning. They are essential for protecting sensitive components from excessive current and ensuring that circuits operate within their specified parameters. Without resistors, many electronic devices would malfunction or become damaged, highlighting their importance in the design and functionality of electronic systems.
