Unformatted text preview: current. We then ran the same set of experiments on a similar circuit that had a rheostat connected. The final circuit had three different circuits linked together that were capable of being bypassed if so desired. All combinations of this resistor were tested as well. The data gathered by all this was used to find the following models: I = [4.63 volt]1/R + .0117 amps I = [.0406 1/ohms]V -.00646 amps These compared well with the general formula of V=IR. This was also the same as our original predictions from the beginning of the experiment. Further questions: 17) The sliding portion of a resistor changes the voltage across a current by affecting how much of the current is moved through the resistor coil. This affects how the voltage changes across the resistor....
