Typically, yes.
It is a resistor which resistance is changeable, such as a potentiometer.
A potentiometer.
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.
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.
A variable resistive device
A potentiometer is a variable resistor used in electronics.
It is a resistor which resistance is changeable, such as a 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.

The volume knob on an audio device (radio, TV) is an example of a variable resistor. A variable resistor is also known as a potentiometer.

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

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!
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.
