Chapter 25, Problem 67P
The voltage on a charged capacitor is monitored with a voltmeter whose resistance is 1.00 MΩ. The table below gives the meter reading as a function of time. Determine a function of the voltage which, when you plot it against time, should give a straight line. Make your plot, establish a best-lit line, and use it to determine the capacitance.
| Time(s) | 0 | 1 | 2 | 3 | 4 |
| Voltage(V) | 15.0 | 10.3 | 6.36 | 3.78 | 2.43 |

In the last column in the data table, it says that it's about voltage(v) divided by current(A) is equal to ohms so V/A = ohms.
So if it's V/A and if you divide them to get the slope it's (y2-y1)/(x2-x1) then shouldn't V be the y value and A be the x value?
And can you also try to use a line of best bit instead of drawing the line through each dot?
Based on the % error calculations in procedures B, was there a significant difference between the measured and theoretical values for capacitance? What factors do you think affect the calculation of the % error may it be significant or not?
Based on the % error calculations in procedures A, was there a significant difference between the measured and theoretical values for capacitance? What factors do you think affect the calculation of the % error may it be significant or not?
