A "control" cell in an experiment is a cell for which the physical properties are known. Control cells are used when you want to evaluate the effect of a new fabrication process or technique, but you also want to be sure that the results are not contaminated by some unaccounted for variable.
For example, in the manufacture of integrated circuits, you may wish to evaluate the change in circuit performance when you shift the voltage threshold of your transistors. You would fabricate a control cell using the normal process, and an experimental cell using the new voltage threshold process. The circuits would be fabricated together on the same equipment, using the same processes, except for the one step where the voltage thresholds vary. That way, when you see a performance difference between the control and experimental cells, you can be assured that the difference is due to the voltage threshold difference, and not some other process.
What else can I help you with?
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is an experiment that does not contain a variable?
The control does not contain a variable!:)
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What does a control group have to do with the independent variable?
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
What is the difference of independent variable and a dependent variable?
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,

What is a the difference between a control and a variable?
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
Variable that doesn't change in an experiment?
The variable in an experiment that remains the same is known as the control.
What is an experiment that does not contain a variable?
The control does not contain a variable!:)
What variable is an experiment control?
The variable that stays the same
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
