An experiment is set up to determine the best voltage for electroplating tin onto iron. Iron plates are suspended, at constant temperature, in an electrolyte solution and wired through a rectifier. Different voltages will be set on the rectifier and then after a set amount of time, the plates removed and the thickness of the layer of tin measured with calipers. One iron plate will be placed in the electrolyte solution with no voltage passing through it, and one plate will be placed in with the maximum voltage the rectifier can produce. Please identify,in this experiment, 1) The Independent Variable 2) The Dependent Variable 3) The Positive Control 4) The Negative Control 5) Constants
