Questions with Rotary Potentiometers, Rheostats

  • Ask: How does a rotary potentiometer work?

    Answer: Rotary potentiometer (the most common type) vary their resistive value as a result of an angular movement. Rotating a knob or dial attached to the shaft causes the internal wiper to sweep around a curved resistive element. The most common use of a rotary potentiometer is the volume-control pot.

  • Ask: What is the difference between A and B potentiometers?

    Answer: 500k "A" would denote an audio taper pot, and the "B" suffix would denote a linear taper pot. The only difference is the taper of the pot, or "how gradually it rolls off". Most manufacturers use either (2) audio taper pots for volume + tone or would use audio taper for volume, and linear taper for tone.

  • Ask: Which type of potentiometer is used for volume control?

    Answer: A potentiometer is also commonly known as a potmeter or pot. The most common form of potmeter is the single turn rotary potmeter. This type of pot is often used in audio volume control (logarithmic taper) as well as many other applications.

  • Ask: What is rheostat and its function?

    Answer: A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... Rheostats were often used as power control devices, for example to control light intensity (dimmer), speed of motors, heaters and ovens.


  • Ask: How do rheostats work?

    Answer: Rheostat is a type of variable resistor, whose resistance can be changed so as to change the amount of current flowing through a circuit. ... Some rheostats have three terminals just like potentiometer, although only two terminals are used (Only one of the two fixed terminals and the moving terminal are used).

  • Ask: What is the difference between a potentiometer and a rheostat?

    Answer: A potentiometer is a three terminal variable resistor, but a rheostat is a two terminal variable resistor. A potentiometer can be used as a rheostat but a rheostat cannot be used as a potentiometer. Potentiometers are often used to vary voltage and rheostats are used to vary current.
