What are uses of potentiometer?

A potentiometer is a variable resistor used in electronics.


What does a variable risistor do?

It is a resistor which resistance is changeable, such as a potentiometer.


What is another term for potentiometer?

A potentiometer and a rheostat are two different applications for a variable resistor.A potentiometer is a variable resistor, connected (using its three terminals) as a variable potential divider.A rheostat is a variable resistor, connected (using two of its three terminals) to adjust current.

What do you call the variable resistor when it is set up to alter the size of the voltage over the resistor?

A potentiometer.


What is the name of a variable resistor with 3 terminals?

It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.


What is a resistor that can be adjusted between minimum and maximum by turning a dial is called a what?

It is a variable resistor. Basically, the same as when you turn up or down the heat on an electrical oven or radio.


What is the function of rheostat in this experiment?

A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.


Is a 47 K variable resistor the same as a Potentiometer?

Yes, a variable resistor is the same as a potentiometer, or pot in short is what it's also called. Trimmer is also often used. Most volume knobs or volume sliders are similarly also potentiometers. Hope this helps!


What is advantages and disadvantage of potentiometer?

Potentiators works well as a voltage resistor or variable resistor. It is often used for volume controls on a radio, but they can be cumbersome.
