A controlled variable is one which is not allowed to change unpredictably during an experiment. Because they are ideally expected to remain the same, they are also called constant variables.

An example of a constant variable could be the voltage from a power supply. If you are examining how electricity affects an experimental subject, you would keep the voltage constant, as otherwise the energy supplied would change as the voltage did.

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.
