Relationship Between Resistance And Current And Graph 1: Resistance Vs. Current

As seen from Graph 1 (Resistance vs. Current) there is not any particular significant relationship between resistance and current. According to Ohm’s Law, when resistance increases, current should have decrease or vice versa. There is no such display of that kind of relationship in Table 1 and Graph 1. The data does not make sense since in a circuit, the current and resistance should influence each other in some type of way. The data did not agree with the expectations. According to Graph 2 (Voltage vs. Current), again, there is not any particular relationship between voltage and current. According to Ohm’s Law, mathematically, when voltage increases, current should also increase and vice versa. The data is not reasonable since voltage helps power the current, there must be some type of relationship between the two. But the data did not agree with the expectations. Kirchhoff’s Law was applied when the circuit was interrupted to measure the current. Revisiting the schematic figure of the circuit (figure 8), when any of the resistors was removed, this should not affect any of …show more content…
The only benefit to students was familiarizing themselves with building a circuit. It failed in helping students gain a better understanding of Ohm’s and Kirchhoff’s Law. When viewing the relationship between resistance and current and voltage and current, Ohm’s Law was not applicable. In theory, according to Ohm’s equation, there is an inverse relationship between current and resistance. Contrary, there is a direct relationship between voltage and current. According to Graph 1 and 2, these relationships cannot be seen and this was unexpected. Regarding the concepts with Kirchhoff’s Laws, it can only be conceptual in this experiment. The method of data recording was inefficient. Conclusion cannot be drawn from the specific data. However, conceptually, students can see the construction of junctions and loops in a circuit from figure
