For example, a variable resistor can be used to adjust the brightness of an LED, or to tune the frequency of an oscillator. Add your perspective Help others by sharing more (125 characters min ...

A 1-kΩ resistor, for example, has a rise time of less than 1 nsec without ringing. Rise time depends on resistance value, but higher and lower values are only slightly slower than midrange values. The ...

What does variable resistor actually mean? ... An electronic component that is used to vary the amount of current that flows through a circuit. ... In this example, ...

In this tutorial we will show you how to get the variable regulated Voltage from the LM317 IC. With a small circuitry attached with LM317 we can get variable voltage up to 37v with 1.5A max current.

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls ...
