A controlled experiment is different from others since it has the same amount of things except for only one variable. For example of a controlled experiment, If you have two plants and you want to see if it will grown better in sunlight or in darkness. So you put on in the closet and put the other one in a open window. You water and give both of them the same amount of soil, water, ferterizer. Except for the one variable which in this case is sunlight.
They make a controlled experiment.
You can only change ONE at a time. That's what makes it controlled. It's the only sure way to know what actually changed the experiment.
An experiment is considered controlled when all variables are kept constant except for the one being tested. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment. Controlled experiments help establish cause-and-effect relationships between variables.

Who are the 'others'? Unless I know that I can not answer your question.
If you have multiple uncontrolled variables, you can't tell which one (or which combination) is causing the change. For example, if you put four different random chemicals in milk and it exploded, you wouldn't know which of the four chemicals makes milk explode, or if it takes a combination of those four chemicals to cause the explosion.
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
