Resistors

As a basic and essential component in a circuit, a resistor's main function is to limit the flow of current. Through this function, it achieves key functions in the circuit such as reducing current, distributing voltage, and setting bias levels. Resistors are divided into two categories: fixed and adjustable. Fixed resistors have a fixed resistance value and are suitable for parts of circuits that do not need to adjust the resistance. In contrast, adjustable resistors (such as potentiometers) provide The ability to adjust the resistance value allowing the user to adjust it within a certain range as needed.

When selecting a resistor, its resistance value is the primary consideration, but power capacity, physical size, and temperature coefficient are also important parameters that determine its suitability and performance. The correct selection of resistors is critical to ensuring stable operation and performance of the circuit.
