If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.
Variable resistor. The value of the variable resistor can be changed at any given moment.
A potentiometer.
Typically, yes.
It is a resistor which resistance is changeable, such as a potentiometer.
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.
how do test a variable resistor
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
yes, a variable resistor
Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
its the colour of the fixed and the variable we define it by its power and name
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.

A variable resistor diagram illustrates how a resistor can change its resistance value, allowing for adjustable control of electrical current in a circuit.
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
no
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
