experiment were red, red, brown, and gold as well as gray, red, and black. This meant that the values of the resistors were 220Ωand 180Ωrespectively.When comparing the slope to the value of the resistor, we obtained a percenterror of 1.5%. This value is very accurate as it is less than 5 percent off from the GAV. Using these values, we found the total resistance to be 400 Ω. We calculated the current to be 0.014 A. We calculated the voltage for resistors one and two to be 2.72 V and 2.23 V respectively. Overall, our calculated values and measured voltages and resistances were accurate.For the next part of the experiment, setting up resistors in parallel, we obtained an average slope of 97.7 Ω. Similarly, the resistance for resistors 1 and 2 were 220 Ω and 180 Ω respectively. The value of the resistor compared to the slope had a percent error of 1.31%. This means that this value is accurate and relatively close to the GAV from the resistors. Using these values, we found the total resistance to be 99 Ω. We calculated the
total current to be .0498 A. We calculated the current for resistor one to be 0.0225 A and the current for resistor two to be 0.0273 A. We calculated the voltage for resistor one to be 5 V and the voltage for resistor two to be 5 V. The percent error for voltage one was 0 % and the percent error for voltage two was 0 %. This data showed to be very accurate.Overall, I would consider this experiment to be successful. We successfully observed Ohm’s Law at work in DC circuits. With resistors in series, the current was the same and the voltages were different through each resistor. With resistors in parallel, the currents were different and the voltages were the same through each resistor. 7
