A variable resistor is used in cicuits to vary the current passing through the resistor. It is commonly used to change the value of current across a circuit, or to act as a voltage divider.
They are commonly equiped with a knob outside of a cabinet, to enable the user to adjust the operation of a circuit, like a volume control on a radio or amplifier.

What is the purpose and functionality of the address operator in C?
The address operator in C is denoted by the symbol "" and is used to retrieve the memory address of a variable. This allows programmers to access and manipulate the memory location of a variable directly, enabling more efficient and precise control over memory management in their programs.
What is the use of void pointer?
Void Pointer is a General purpose pointer ,that does not have any data type associated with it and can store address of any type of variable. Declaration: void * pointer_name;
Is D a good variable name?
Variable names should show what data the variable holds so others reading your code will understand it. For example, a variable holding the age of a user should be called "age" or "user_age", or something similar.
How does a technological system adjust itself?
it haves a sstem of parts
What do the percent signs in SystemRoot represent?
Substituting environment variable valuesTo enable the substitution of variable values at the command line or in scripts, enclose the variable name in percent signs (that is, %variablename%). By using percent signs, you ensure that Cmd.exe references the variable values instead of making a literal comparison. After you define variable values for a variable name, enclose the variable name in percent signs. Cmd.exe searches for all instances of the variable name and replaces it with the defined variable value. For example, if you create a script that contains different values (for example, user names) and you want to define the USERNAME environment variable for each user with these values, you can write one script using the variable USERNAME enclosed in percent signs. When you run this script, Cmd.exe replaces %USERNAME% with the variable values, which eliminates the need to perform this task manually for each user. Variable substitution is not recursive. Cmd.exe checks variables once. For more information about variable substitution, see For and CallFrom the above Technet description, the % signs are used to ensure that "cmd.exe" does not literally use the term "systemroot" and references the systemroot variable correctly (So therefore %systemroot% is recognised correctly as the C:\ drive, if C:\ is your systemroot).
What is an idependent variable?
It is the kind of variable that you purposely change.
What is the dependent varible?
The dependent variable ( responding variable ) is the variable that changes on purpose.
Which variable is changed on purpose?
constant
Does manipulated variable mean changed on accident?
A manipulated variable is not changed on purpose.
The factor in an experiment that is changed on purpose?
The factor in an experiment that is changed on purpose is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable. It is the cause being studied in the experiment.
What do we call the variable that you change on purpose?
The variable that is intentionally changed in an experiment or study is called the independent variable. It is manipulated by the researcher to observe the effect it has on the dependent variable.
What is a maniuplated variable?
A manipulated variable, also known as an independent variable, is the variable that is intentionally changed or controlled by the experimenter in an experiment. Its purpose is to determine the effect it has on the dependent variable.
The variable not related to the purpose of th study but may affect the dependent variable are termed as extraneous variable true or false?
False: they are called exogenous.
What is the purpose of initialising an array?
Arrays are variables, so your question is: What is the purpose of initialising a variable? Answer: assigning initial values to them.
When solving by the substitution method what happens when one variable cancels out?
That's exactly the purpose of the substitution method ... to get an equation with one less variable. When you have it, you solve it for the variable that's left.
What is the purpose of set-up A?
So you can make sure the results you gain are only due to the independent variable and not a variable not being tested.
Can the independent variable and the control variable be the same?
No, the independent variable and the control variable cannot be the same. The independent variable is what is being changed or manipulated in an experiment to observe its effect on the dependent variable, while the control variable is kept constant to minimize its impact on the results. Having them be the same would defeat the purpose of having a control variable.
