Resistors in series and parallel combinations In the “Deviation from Ohm’s law section, we basically used the same set up as the first experiment on verifying Ohm’s law, but this time we measured the IV Linearlized graph for RC circuit 0 3.00E- 02 3.50E- 02 4.00E- 02 4.50E- 02 5.00E- 02 5.50E- 02 6.00E- 02 6.50E- 02 7.00E- 02 - 0.5 - 1 ln (Vb(V)- - 1.5 V(V)) - 2 - 2.5 y = - 90.463x + 3.1199 - 3 - 3.5 time (s) Graph 4. Linearized graph for RC circult. We only analyzed the portion where the voltage is maximum and stable. We linearized the data as we did in part 1, since the voltage of the capacitor has an exponential dependence on time. Expectedly, there is a negative linear relationship between the natural log of Vb- V and time. Standard Coefficients Error Intercept 3.11989 0.09121 B - 90.46261 1.72244 Table 5. Linear regression of data used in graph 4. The slope of the graph is - 90.46261 with an error of 1.722. There’s a strong linear relationship between the ln of voltage and time, which verifies the exponential...
