Experiment 3: Ohm's Law Date: 22.03.2004 Objective: 1) To investigate the relationship between the variables V, R, and I in an electric circuit. 2) To analyze series and parallel connection in terms of V, R, I 3) To determine the relationship between current and voltage in a circuit that contain a filament bulb Theory: It is known that electrons flow through a conductor metal wires with an ease without any resistance. This means that nothing would prevent the flow of the electrons. In a normal case however, under normal conditions, a resistance in the wire would affect the flow of the electrons in much the same way that friction slows down a sliding box on a platform. To allow more electrons to move against the resistance of a wire, it is necessary to apply a potential difference between the two ends. One can calculate the potential difference needed to create...
