Volts Vs. Current
In this experiment voltage was passed through an Amp reader and then through a resistor. This was done for various different power outputs in order to obtain the different readings in current and voltage.
The picture above is a comparison between our resistor and the resistor from the group beside us.
The above picture is our data in comparison with the other groups 2 data.
The data above displays that voltage is proportional to current. Our data is in blue while the other group's is in red. The fit line displays our graph as a voltage versus current graph using the equation V=IR. Moreover, our slope in this case is our resistance in our resistor in which case we concluded that the other groups resistor was strong than ours. Even though we both had very similar resistor, our difference in resistivity may be due to the systematic error in different equipment.
Resistance Lab
The above photos display the equipment used to calculate the resistance in different resistor of which each had a different length and/ or material, copper or nickel.
The above picture is our data collected from the experiment and the graph was plotted as Length versus Resistance. From this graph it was determined that in resistors of same material and diameter have a proportional relationship between length and resistance. However, when the diameter of the wire increases and the length is consistent then the resistivity decreases as the area of the wire increase. Therefore, displaying an inverse relationship. As shown in the picture below.
