With this equipment, we measured the relationship between voltage, resistance, and current. All% mistakes in the first experiment are within the set tolerance of 10%. The graph depicting the mathematical relationship between current, and resistance illustrates that as resistance increases, current decreases while voltage remains constant. Furthermore, the mathematical relationship between current and voltage shown by the graphs on Constant Resistance reveals that as the current grows, so does the voltage. In a series circuit with connected resistors of equal resistance, the total resistance is represented by the sum of each resistor's resistance times the circuit's resistor count. For illustration, connecting two identical resistors in series results in a total resistance that is twice that of a single resistor. The total resistance of a series of three identical resistors is three times that of the first resistor, and so on. When equal resistance resistors are connected in parallel, the overall resistance is represented by the sum of the individual resistor values divided by the number of resistors in the circuit. This demonstrates that as more resistors are added, the overall resistance lowers. In a series circuit with equal resistances, the voltage is spread equally among the resistors. This means that the whole voltage supplied by the power source is distributed evenly among all resistors. The resistance of each resistor is inversely proportional to the voltage across it. In a parallel circuit with equal resistance, voltage distribution follows a pattern in which each resistor receives the entire voltage supplied by the power source. The resistance of each resistor determines the amount of current that passes through it; the lower the resistance, the more current flows through that particular resistor. Moreover, in a series circuit with equal resistances, the current flowing through each resistor is inversely proportional to the resistance value. The total current in a parallel circuit with equal resistances is shared equally among the circuit's branches. Additionally, because each branch provides a distinct path for current to travel through, the total current equals the sum of the current passing Report for Experiment PhyII-02: Basic Electricity Page 7 of 8
