Resistors

Resistors are passive electrical components with two terminals–designed to control the specific amount of electric current flow in multiple electronic circuits–by introducing resistance. They are fundamental components in electronic devices and complex computer systems and come with different resistance and tolerance values. Resistors also come with a power rating, indicating the maximum amount of power they can dissipate without overheating. A resistor is significant for designing circuits with desired operating characteristics. Resistors are usually colour-coded for easy identification of resistance value and come with a different resistor symbol, depending on the circuit diagram and types. 

Versatile Functions of Resistors

The primary function of a resistor is to provide a specific amount of electrical resistance, typically measured in ohms (Ω). They are also used for a variety of purposes, including voltage division, current limiting, signal conditioning, impedance matching, current measuring, and terminating transmission lines.

Why Buy Resistors? Exploring the Benefits

Resistors are electronic components that serve multiple purposes. Buying these cost-effective resistors allows users to tailor and optimise electronic circuits, ensuring proper functionality and performance. Resistors are indispensable components in electronics, providing essential control and optimisation for various applications.

Popular Types of Resistors

There are various types of resistors, including:

  • Fixed Resistors – Fixed resistors have a constant resistance value and do not change their resistance.
  • Variable Resistors (Potentiometers) – These passive components allow you to adjust the resistance by physically turning a knob or sliding a slider.
  • Thermistors – These resistors have a resistance that varies significantly with temperature. They are used in temperature sensing applications.
  • Light-Dependent Resistors (LDRs) – LDRs change their resistance based on the amount of light they are exposed to. They are used in light-sensitive applications like automatic streetlights.
  • Resistor Networks – These resistor arrays consist of multiple resistors packaged together in a single component.

Other Common Resistor Types Include:

  • Carbon Film Resistors
  • Metal Film Resistors
  • Wirewound Resistors
  • Metal Oxide Resistors
  • Metal Strip Resistors 
  • Thick Film Resistors
  • Surface-Mount Resistors
  • Through-Hole Resistors
  • Specialised Resistors
  • Thin Film Resistors.
