An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...
Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...
Resistors are one of the most basic yet crucial components in all electronic devices, but what do they actually do, and how do they work? In this video, we’ll break down the fundamental concept of ...
A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...
Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...
The VRH320 Variable Wire Wound Resistor available from ARCOL Resistors has a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment, instruments, ...
TT Electronics has aded four new product families to its variable resistor portfolio. These include three new encoder lines and a new line of single turn potentiometers. These products are suitable ...
I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 ...
Very often when simulating an electrical circuit in SPICE, there is a need for a variable passive element such as a resistor, a capacitor or an inductor. Very often when simulating an electrical ...
Variable resistors have many practical applications including volume controls, eg on a radio, and speed controls, eg on a mixer or a drill. There is usually a dial or sliding switch on the variable ...
A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...
