Introduction: For this experiment, the purpose was to understand the relationship about the electrical quantities: current, voltage, and resistance. These three quantities’ relationship that we used in this lab is known as Ohm’s Law. According to this law, “the current through a resistor is proportional to the potential difference across the resistor.” The mathematical representation of this law is V=IR which helped us understand series and parallel circuits better. Using Ohm’s law we calculated equivalent resistance of series and parallel circuits and also took a look at current flow and voltage with their relationship to series and parallel circuits. To begin the experiment, all the appropriate materials must be connected correctly. Jay’s TI-83+ calculator was connected to the LabPro and then current and voltage probes was plugged into the Dual Channel Amplifier which was connected itself to the LabPro. Once everything was connected, the calculator was turned on and the program DATAMATE was started. While the power supply was off, our T.A., Alec Sim, connected the series circuits to the 10 ohm resistors which went through the current sensors. Switch 1 was turned to the off position so the voltage meter could be ready to make the first measurement across
