Resistors are passive electronic components that are widely used in electrical and electronic circuits. They are designed to resist the flow of electric current and provide a specific amount of resistance to the flow of electrical charge.
They can be used to adjust signal levels, divide voltages, limit current to LEDs, and perform other functions.
There are various types of resistors available, including through-hole resistors (axial lead or radial lead), surface mount resistors (SMD), variable resistors (potentiometers and rheostats), and specialized resistors for specific applications like high-precision resistors, high-power resistors, and temperature-sensitive resistors.
It's important to consult the datasheets and specifications provided by manufacturers to ensure that the chosen resistors meet the requirements of your specific application.
